While on AP for most of a 50mi commute this morning I have 60%+ Unsafe Follow Distance (still rated the trip at a 99 score lol). All non-AP driving was at less than 50MPH which supposedly will never trigger USF. I don't think they know WTH they're talking about. Theres some disconnect between the engineers that wrote the thing and the tech doc publishers that wrote the description page
The current AP system clearly has no clue, especially with vision only, how to accurately discern distance. Everybody is getting dinged on following too closely. I have it on 7, drive like a granny, and when hand driving, I'm sooooo far back from people, even while on AP, it should never ding me.
EXCEPT!!! When stopped, the car launches from 0-15mph like a banshee and is on the arse of the bumper in front of you, then it just lifts completely off the accelerator, and starts going at a snails pace...that is probably part of the following too closely.
Next, when slowing/stopping, the car can never get that correct and will jam on the brakes way too late, or if rolling slowly in stop go, it is hit/miss how far it will stay away from the car ahead of you. I'm constantly doing what the car should be able to do, I'm slowing it by scrolling the wheel back every few seconds as I see traffic stopping/slowing ahead making ACC slow down and keep it's distance and not slam on the brakes like it will do. Then I ramp the wheel back up, or just stop it from AP while stopped to make it quit launching stupidly. People are getting so furious with the cars behavior behind me. It launches, then it crawls, people dive bomb in front of you. The car is doing things that make it more dangerous as a driving on the road for you and others. Anybody that denies this must be worried about their stock price in TSLA. No half-sensible person would start/stop like the car currently is doing. Hence, the follow too close is starting to add up on me.
I seriously have no idea how I can follow any further and do any better using AP "correctly" since all my hits on following too closely have to be due entirely to AP/FSD itself.
With that said, I'm still hanging onto a 100 right now...going to start hand driving more in particular situations, especially when stopped, so it won't launch and ride the bumper in front of me or drive too close even on 7 in particular situations. Otherwise, it is out of my control as usual. The car is calculating something in particular situations, while rolling slowly or who knows what...to think you are an unsafe driver.
