why do you think the floor grid is for measuring?

It's to determine velocity of a point or object they want to measure using two frames of video.

If you know the vector and weight of a piece that goes flying off you can determine its energy. Thats kind of important in a crash test.

I, for one, will be interested to find out who is correct. I know who my money is on.

(2) total vehicle length of 223" (+/-1.5") (btw, for folks using the squares on the floor, perspective kills you bc the floor is a good 3-4' further away from the waistline of the CT); notably, this reduced length from unveil stats (231.7") both (A) is notionally consistent with a narrowing of the wheelbase, for proportion's sake, and (B) would make the CT that much more competitive against the size issues presented by other full-sized trucks. Specifically, at this reduced length it would fit more easily in several garages, and provide a more city-appropriate turning radius/maneuverability.

(3) width at tailgate of 75" (consistent with prior thread's estimates, and dead-on to @JBee 's contribution to that thread)
There is simply NOOOOO way it is 223 x 75, NEVER.

Thank you for your effort, but IMO you are wasting time, yours and other's. Only if those pictures were taken far far away, otherwise, it is useless to get accurate measurements.

GOT THE TIRE SIZE........... ?

(it's at 7 o'clock if you're blind)

285/65R20 That's a 33" tire
I thought that size has a 34.6" OD. Pretty close to 35" as we'd been told...

I didn’t go with the tire for the measure reference only because I thought the true ā€œedgeā€ may be a bit hard to find - or defend :LOL:
What did you use to measure???? I just see no possibility this has my same long bed Tacoma wheel base as you measured, but the tires sit where they do.
I am less confident in your dimensions than MDRs. I tried to measure the stainless yesterday and LiDAR doesn’t like stainless. I doubt his dimensions too.

how did it come out to OG size. Makes no sense. Unveil can’t coke fast enough.

I am still positive about 227.5

Of course a very slight size increase of the rim would indeed make the whole CT bigger with the scaled measurements, and I'm Ok with that. Again, awesome work.

Collectively, y'all two win the April 1st prize.

The CT crash prototype is nearly identical to the unveil on-screen specs.
  • wheelbase is ~142"
  • max width flare-to-flare ~82"
  • max width metal-to-metal ~78.5"
  • length nose-to-tail ~230"
the above within +/- 1-2" margin of error I'd guess

And it proves a point about the sort of conduct on this forum.

Funny thing is, the ACTUAL possible source of material error in my measurements was my stated assumption about the rim's lip height. My stated assumption of 21," if off by only 1," would distort all subsequent measurements by 4.5%. That 4.5% is the difference between an F150 and (nearly) a Tacoma.

Stepping right over that all-critical assumption, the most Kool-Aid drunk amongst us instead doggedly fought about 'lens distortions,' perspective, and even how rulers measure. (!?) They continued to do so even in the face of researched, accurate, proofed-up refutations of those myriads of armchair chirps. (I'll return later to again prove up my positions on those topics.)

Yet the actual critical and flawed stated assumption was right there in the OP:

the CT's tire sidewall shows it's on a 20" rim as reference... the outermost lip of a rim is a bit wider than the designated width of the wheel, typically by ~0.5 inches all around... Accordingly, I measured the rim reference as 21" (in red):
Some 10 minutes of research could have solved it. One could have just looked at the sidewall, seen it was a 285/65/r20 (I referenced its availability just above), and so a 35" tire. Then, with 2 minutes of an online measurement tool (which I used in my OP as a breadcrumb, despite having access to measurement software), just plugged in a 35" tire reference measurement and found the rim is 22" not 21":

Alternatively, for those feeling short on time or uninterested in research, the flaw in the methodology could have been most quickly and effortlessly determined by any version of a single question that was both skeptical and generous to the efforts and possible expertise of others:

"I'm surprised by these results - what would you say is the biggest possible point of error in your assumptions?"​

Whether being handed the answer because you asked nicely, or because you cared to spend fraction of your time actually contributing, you might have in either event gotten what your inner child was demanding: pretty damn good proof the CT exterior is near dead-on of the unveil on-screen specs.

But instead only: "you're wrong, and I can prove it by saying 'perspective'... a lot."
This is a fairly typical dynamic here. Maybe I bring it out in people. But I see others subjected to it as well. (Though they're smarter than me, and relent/stop participating sooner.) I'm also probably guilty of it at times (glances at Mr. "parasitic profiteer"). But there are some deep, repeat, offenders.

There was a silver lining to all this subterfuge: it was kind of fun. I've never had good occasion to pepper a thread with Easter Eggs. But I got to lay several such eggs while the wild goose-chases about camera technology got frothy. I once even mentioned them:

In all, the point of this whole thread was that the Easter Egg within the Tesla crash test video was great ability to make on-screen measurements with even crude tools.
Hell, after @ƆCIII came in and nearly gave it on a silver platter (in the kindest of ways), I thought it was all over. But never underestimate the obstinance of the horde!

Which brings me to the final point: in all of those goose-chases around lens distortions, perspective, measurements, etc., my responses were all pretty dead-on accurate. None of those unexamined, uninformed, critiques explained the measurement issue in OP.

As a final proof of this, here are the actual CT exterior photo measurements which come out to nearly identical (within and still subject to margin of error) of CT unveil stats (although wheelbase appears to have been improved).

Something tells me there won't be such vehement objection to these outcomes, despite all the previously asserted (and re-asserted) assertions about perspective errors being unavoidable in photos. (And if someone still feels tempted, they should know that such perspective distortions in these photos would tend to cause the CT to be in-world larger than these measurements.)

I will say, however, that for the interior photo (you might remember) I didn't use the rim as reference, but instead the checkerboard reference tape on the dummy's seat belt. The CT interior measurements still seem a bit dodgy RE potential interior space being a bit tight. Though (as admitted in OP) perspective is messy in the cabin area (given the nearness of camera and varying depths of objects of interest), so the measurements in this interior pic are more error-prone.

If there's ultimately any truth to the 5% shrinkage rumors, I'm left wondering if it could be largely related to interior dimensions?

A lot of effort for an Aprils's fool... ? ?

But I really didn't have much time to participate, so didn't really concentrate on anything you said, or in particular just how much you said (!), rather was setting up my own drawings instead...:p

Your width measurements are fairly wrong either way, because a) the CT sides are curved and not straight, with the rear doors being just as wide as the outside of the front wheel flares, and b) your internal shoulder height measurements, taken from the overhead shot are not at the correct points, that correlate with the inside door trim underneath. Have a look at the straight red lines and green lines that curve.

There's talented high-effort trolling...and then there's this thread. A new bar has been set, lol. Kudos.

I read the entire thing this morning before you dropped this reveal. I didn't have time to actually check your figures - and my photogrammetry skills are nowhere near your level - but your methodology was obviously fine, with the initial possible rim error caveated.

I was disappointed to think you might be right but forced to consider it possible. The crits leveled at you were frustratingly off-base and obviously emotionally motivated. Admit I did wonder if you were setting traps at times, but I didn't see the reveal coming.

Nice one. I'd have been much less kind, haha.

A lot of effort for an Aprils's fool... ? ?
not as much effort as I’ve spent collectively over dozens of threads witnessing the same exhausting pattern as seen in this thread.


For just one example of category, to date, on this forum, myself (and others I’ve watched) have done little more than draw ire and belittling for even the most honest attempts at discussions about the F150 Lightning. Post something critical of the F150 and it’s all pats on the back. Post something favorable, and you get shouted down. By people who don’t own one. Or who just step over stated qualifications in order exercise their demons by just dropping into a conversation to drop a turd in the punch bowl.

I’ve had so many recent ā€˜spats’ on here of the same nature as how the measurement thread devolved - as I’d expected it would. No matter how deeply caveated, nor how deeply researched, a person posts something on this forum that gets interpreted as skepticism of the kool-aid hordes favorite ideas, and it gets shouted down. Post instead an exactly equal amount of conjecture on a point that’s kool-aid approved, and it receives only qualified pats on the back.

Many classic examples are through this thread. In this extensive thread with supporting research but suggesting the CT is shorter than expected, one member chimes in repetitively only to say that perspective makes the effort meaningless. But in another thread, absent any supporting research or explanation, someone uses the photos (quite sloppily) and measurement techniques employed here to assert the CT is as long as expected, and that very same member comes in to say ā€œthat’s exactly right.ā€

It’s ridiculous, intellectually dishonest, and frankly - makes this forum a rather hostile place to be for anyone looking to have reasoned discussion about both the amazing and skepticism-inducing features of the CT as presently known (or any competitor vehicle). It’s an echo chamber of shouting.

And predictable. I knew a thread ā€œproving upā€ near-Tacoma like proportions would bring out a few of the worst offenders. And as it was April 1st…

But maybe I’m just too jaded. After-all, who in their right mind spends this much time and effort to play a petty April Fool’s joke that is a meta-level critique of that behavior.

But speaking of attempts to have honest discussions (full of caveats!) about both the amazing and skepticism-inducing features of the CT: the interior dimensions of the CT.

But first here’s the (I think) unnecessary and obvious caveats, that will be ignored entirely to add air to the shouts: we won’t know the CT’s real interior dimensions until officially released, and interpreting currently available information is rife with issues of accuracy…

That caveat laid out:

your internal shoulder height measurements, taken from the overhead shot are not at the correct points, that correlate with the inside door trim underneath.
the source of the above comments confusion is entirely on me, and the subterfuge of this this thread: I don’t stand behind the OP post shoulder width measurements taken from the exterior (which were all incorrect by design).

Conversely, the interior photo is a different matter. though rife with its own issues of accuracy, there do exist the checkerboard measure reference boards on the dummies that provide some modestly interesting insights to some interior scale. if nothing else, I *think* the two front seat dummies are the female versions of the ā€œHybrid IIIā€ dummy - which if so are pretty small dummies. Dimension can be found out there for those interested.

In any event, the interior dimension measurements both in my OP and last nights measurements I heavily caveated. The overhead dimension from OP I don’t stand behind.
