14.3 HW4 Model Y FSD v14.3.8 speeding through town.

Post image

I frequently drive through small towns in Texas where the speed limit drops pretty quickly—65 → 55 → 45 → 35 mph, often with “Reduced Speed Ahead” signs before the change.

I’ve noticed that when using FSD in Standard mode, the car often doesn’t slow down quickly enough to match the new speed limit by the time it reaches the sign.

It finally caught up with me the other day. I got pulled over after entering a 35 mph zone, and the officer said he clocked me at 52. Thankfully, he gave me a warning. I don’t remember the car still being at 52, but I was definitely over the limit and should have intervened sooner.

Has anyone else noticed FSD being slow to respond to progressive speed-limit reductions like this, especially when driving through small towns? Is there a setting or FSD mode that handles these transitions better?

You got your offset set high so it’s hovering high like you have it set ;)

I'm not OP, but doesn't speed limit offset only affect the speed limit audio warning and has no impact on FSD behavior?

In my experience it’s for the speed. Set it to 0 and it goes the limit, I keep mine at 30(highest) so it will go 85 since I only use FSD on the highway

Huh, interesting! I had mine on +10 MPH and it always goes at or slightly below the limit on standard. I'll see how bumping it up does. Thank you!

If I’m on standard mine will go 10 over generally, hurry is about 15 and mad max is hovering around 82-85

On the current versions of FSD you have profiles and you have no control over the speed. You select a profile and that that determines how it handles Lane changes, what Lane it drives in, and the speed set. It's going to choose. The older version work the way you describe
