Meh, still looks rather anemic for 4-wheel steering to me.

I am with-holding further judgement 'til I see it parallel park.
That's fair. However, anything better than my F-150 will make me happy.

As the CT is quite large and will be difficult to drive in the city as compared to the 3 or y, I am wondering if rear wheel steering will be in all models or just the high-end tri or quad motor levels.

Probs all.

They don't usually differentiate aside from battery and motors.

For production line simplicity

I'm not so sure rear wheel steering actually decreases the turn radius much at all. I think it does decrease the turn radius a little bit but the biggest advantage it confers upon tight space manuevering is it prevents the rear wheels from dragging to the inside of the turn. That means you can start a tight turn sooner without dragging the side of the vehicle across the obstruction.
If park my F150 nose-in a parking spot and the lot is full and tight, I may not be able to leave. I can't start turning until my entire 22' truck is clear of my spot and the cars next to me. If I back into the spot, I can start turning earlier which allows me to pull out of tighter spots. If the rear wheels don't drag the inside of the curve, it'll let me turn sharper.
True. But it's also true that some will argue the Earth is flat...I'm just saying...
We know the earth isn't flat because if it were, cats would have shoved everything off the edge already. :ROFLMAO::p

If the Earth Really Is Round, Why Are There So Many Globes Everywhere?
Kandiss Taylor, a former Georgia gubernatorial candidate, is a flat-Earther convinced that globes are part of a bigger conspiracy.

“Everywhere there’s globes…and that’s what they do to brainwash… For me, if it is not a conspiracy, if it is, you know, ‘real,’ why are you pushing so hard? Everywhere I go, every store, you buy a globe, there’s globes everywhere—every movie, every TV show, news media, why?”...

Taylor’s comments came during a broader conversation focused on the flat-Earth conspiracy theory; the conversation featured “Flat Earth Dave,” who manages a website with the same moniker.

Yeah, that's what I said.

My point was the benefit of rear-wheel steering will show up more in actual manuevers than in a dramatic reduction of minimum turning radius spec (but it will help reduce it somewhat).

...

TLDR (or Too hard, didn't read... LOL):

CONCLUSION
From kinematic analysis, the turning radius of a vehicle can be reduced up to 35% by using four-wheel symmetric steering system without crossing the practical limitations.

Here's the whole study: Lots of Math Article

Area = Pi x (R^2)

F150 = 3.14 x 26.25' = 2,163 ft sq. (curb to curb would have to be 52.5')

F150 with rear steering = 3.14 x (26.25' x .65) ^2 = 914' sq. (curb to curb would have to be 34.125')

Average lane width in the US is 12'.

My current truck takes 4 lanes and a prayer to do a U-turn.
My current truck PLUS 4 wheel steering would take less than 3 lanes to do a U-turn.
My truck and the CT have almost the same wheelbase.

The unknown is how sharp the CT can turn it's wheels, front AND rear.

For this little experiment, I assumed the front wheels turned the same in my F-150 as the CT. I used the same rear-wheel turn angle in each vehicle.

All for fun.

Man, wouldn't it be an absolute hoot if the front AND rear wheels could turn a full 90 degrees? Parallel parking would be SOOOOOO easy!

nor, for the same reasons, did you get into the spot in the first place without backing into it

but having any vehicle, much less one as long as a truck, where the rear end actively swings outwards opposite the turn direction, will require overwriting 30 years of my source code

Remember Tesla sold a “60D” that had a 75kW battery software limited to “60”

but you could decide later to pay for use of the 15kW you were sitting on top of in your car

but hey, Tesla’s basically a charity don’t forget, so there’s no way these other companies are learning about pay-for service features in vehicles from Tesla

I mean, a one time payment is a little more bareable, its like acceleration boost at that point. But a subscription? That'd be crazy.

I don't even pay the fsd one lol

Man I just like the 'sound' toward the end of the video...as it revs up. Am I hearing things?;)
