Why does Tesla recommend a 40% speed offset?

[freyguy]

To me this is asking for trouble!!!

Please comment your current setup what percentage are you using?

to leave this at Tesla recommendation has anyone gotten a ticket or a warning due to this offset recommendation?

I think personally it’s way to high of an offset and not wise to use this.

think about it
25mph will be 35mph
45mph will be 63mph
55mph will be 77mph (here is where we really start flirting with a potential wreckless driving ticket.

seems risky personally

Yeah. It’s pretty crazy. When FSD is in dick mode (Hurry) it’s goes unreasonably fast in socially unacceptable ways. (Traffic merges, school zones etc).
When I tried to reduce the offset, its heavy traffic skills get way worse and it drove awkwardly slow in some circumstances

FSD for CT is amazingly good and yet is surely lacking right now. It definitely needs babysitting while using. I keep reminding myself that they are focused on perfecting FSD for M3 and MY for the big rollout of Robocab, and that they will get to improving the CT FSD later.

Some neighborhoods near me have a 20 MPH speed limit and FSD on the CT with the 40% offset tries to do 35 MPH. Always have to rapidly flick the right wheel down to keep in check.

I find myself with the opposite problem, I often have to hit the juice to make it go faster because I am slowing traffic down. I have mine set to 40%, and I am not a lead foot but even if I scroll the wheel up the truck won't go any faster. Hurry mode seems to help a bit, but most of the time on non-highway roads it's going too slow. I even looked up how to make the FSD drive faster but I found out putting the offset higher doesn't mean the truck will actually use it, it's not like a cruise control speed setting.

Same for me, but I increased the offset to 50%. I am constantly tapping the accelerator pedal to nudge it a little faster.

For city streets, I find that even with the offset set at 50%, the truck rarely goes over 20% of the speed limit. That's mainly because the flow of traffic is moving at the same speed.

For Freeway driving, Hurry keeps me in the number 1 lane between 75-79 when the flow of traffic is going around 80, so I get a few looks. If I switch it to Standard, then the truck tends to travel between 70-74 mph in the middle lanes, still slower than the flow of traffic, which is why I keep tapping the accelerator.

Theoretically FSD is supposed to match the flow of traffic, with the offset being the maximum speed as opposed to a target speed.

When there is little to no traffic, I find it incrementally increases speed very slowly, and then hovers around the speed limit.

Hurry will go faster than the speed limit. Mine typically goes between 82-84 in a 70, but yes, stays in the left lane except to "pass" because it can't understand that just because a car is slightly ahead in the right lane, it's not faster to get over.

Let me explain, on a 20mph zone, you can often see traffic flowing up to 30mph. That’s where the 40% offset will kick in. It is to allow the vehicle to safely follow traffic flow without being limited to a lower speed. Many times going at a much lower speed than traffic flow is dangerous.

I set mine to the highest which I think is 45..? I did so because I noticed the FSD on my CT tends to drive slower, even in hurry mode. On the freeway I always have it set to 85, yet it rarely ever reaches that speed, even with light to no traffic. It seems like it gets caught up slowing down whenever there's curves, etc.

The way I understand it, the offset is not a ‘target’ speed, but rather an ‘allowable’ speed.

 

[REM]

The real answer: The devs at Tesla use California as their base model because it's arguably more chaotic than anywhere else. Most people over there excessively speed to the point where anyone going the actual speed limit are not moving with the flow of traffic.

The onus is on the driver to dial the speed down to something appropriate if it's going too fast in a particular area.

I pretty much can't use "hurry" mode anywhere I live except for the interstate, because it simply drives like a typical a**hole california driver. ?‍

I’m in Texas and use Hurry mode exclusively.

From my view the offset, similar to the top speed zone wheel, creates a max target zone. So if traffic and conditions allow, it will eventually reach that zone. Traffic and conditions are a relative term, as it is a bit opaque as to what the FSD brain perceives. As an example, I drive the same route at the same time every day, mix of city with lots of roundabouts, interstate and rural, and the CT behaves differently every day, even though conditions are mostly the same (to me). The sun is at the same angle, traffic has the similar pattern, similar congestion level and so on. I have cleared the same triple roundabout hundreds of times, and there is rarely any traffic, yet the approach, speed and hesitation varies day by day.
Hurry mode is the only acceptable method for me as all others slow down traffic, and I have set manual overwrites for every speed zone, some are way over as I have a problem in MI with constant construction and the CT still seeing a 35 in a 55 even though the signs were removed weeks ago.
It works in most situations, sometimes I just have to override if it is going too fast, mostly it is the other way around and I need to give it a nudge.

Since FSD started to pass on the right on the Interstate it has become much more enjoyable. What remains annoying is the absolute left lane focus on hurry mode, even though there is no need for it. Standard eliminates the left lane, but also erases a lot of the agility. I never tried Chill, but know that this is not my jam. I don’t drive to chill, I drive to engage.

Talking about annoyances, the slowdown to 65 or below in a 70 zone in a 75+ mph traffic flow before taking an interstate exit that has ample runway just irks me, and equally the drivers behind me. “Here comes the left lane spaceship, that cuts across lanes at the last minute, and then slows down traffic before exiting the race as a last f*** you”. Really unnecessary.

And the turn signal will probably be the 1st thing that will wear out on my CT, 20+ signals for an exit taken from the right lane, really? At what point does signaling become a light show, that would be an interesting debate. There is safety, but there is also silly.

We have a lot of 2 to 4 lane traffic in MI, meaning 1 lane opens up to 2 lanes in the same direction, and coming back to 1 lane after a mile or so. Here FSD has the greatest challenges in my view, as it behaves like a sheep, meaning it follows the vehicle in front of it, which is always the left lane, even though the right lane is open. Why sit behind a cement truck, if you can pass 5 cars in the open right lane and can take pole. If you can take pole, you take pole, always. That seems like a simple algorithm to program. The CT sees the empty lane, but does not react on its own. I usually overwrite with the turn signal, adding to its wear and tear…

In the end it is all good. I would drive and often behave differently in many situations, but then this is me, I am not an algorithm (yet).

I set mine to 15%, I normally speed 10% or max 7mph over. But have to watch it sometimes turning off a 45 road into a plantation, fake signs posed 20 but car still wanna do 52 lol
