Did autopilot distance algorithm change lately?

I have 2019.5.15 and it's really far away from the car in front of me even when selecting '1' for distance. Acceleration from a complete stop also takes forever, but I can live with these problems.

What's really weird is that if I'm on a steep downhill all of a sudden I'm tailgating the car in front of me. It's scary.

Is anyone else seeing this?

For me Autopilot (EAP/FSD) is more 'cautious' compared to TACC. TACC travels noticeably closer to the car in front.

Yes. It's gotten much worse at maintaining a consistent distance from the car in front. I have mine set on 1 car length, and very often there's room for a car to scoot in there between me and the car in front without even affecting what speed I'm going. I've filed numerous bug reports about this.

I too have the same two issues with AP. Selected '1' for the distance but the gap is too long. Accelerating from a stop is sloooow.

Although it's a little too far away, I'm ok with the following distance but the acceleration is painfully slow! I usually end up manually accelerating after traffic stops.

Seems like the follow distance setting is less specific these days. I've also noticed acceleration from a stop is VERY conservative. I wish they'd use the follow distance (1-7) to impact acceleration from a stop as it keeps the distance matched to your setting. That way a 1 setting would have your car accelerate almost immediately.

I use 3 in suburban traffic and 4 on the freeway.

Often I will "help" the car (in traffic) using the accelerator to move off quicker from a stop or close the gap with the car in front. This takes advantage of the car allowing the accelerator without dropping out of TACC or AutoPilot. But I like my default settings.

Haven't noticed the distance issues; the way people drive here, I frequently use 2 on freeways (3-4 if there aren't many cars around or I want to slow down a bit to let someone in without disengaging or reducing my set speed) and 1 in traffic, else you're just inviting someone to cut you off.

Agree that acceleration from a stop is quite conservative, sometimes slow to catch up even after I nudge with the accelerator pedal.

The main changes I've noticed is how smoothly the car slows down when someone slows down or cuts in on the freeway - most of the time it's either as smooth as I would do it, or less harsh than I remember in the case of someone cutting in. If someone cuts in but they're traveling faster then the car doesn't even react anymore.
