James mentions that FSD beta has been improving without any version updates. For example, his car is now slowing down for this hillcrest speed bump:
The only way that's possible is map updates. The car doesn't "learn" on its own, and without a firmware update driving behavior does not change.
Or he's not testing like-like or something (differences in speed, lighting, traffic, etc can all cause different behavior- maybe they repainted the speed bump and it's more visible or something)....Remember the dude who claimed his FSDBeta car "learned" to handle a u-turn, but the videos of it doing it showed the 2 failures were 25 mph faster approach than the 2 "successful" examples?)
Whole Mars said a similar thing about his experience.
And a number of replies from owners on that tweet said they had the opposite experience.
Even when there's ACTUAL firmware updates you can reliably find folks who insist:
The car got slower, AP is worse, battery drains faster, the wipers got worse, the auto highbeams got worse, etc.
and often in the same thread, people who got the same update in the same model, insisting:
The car got faster, AP is better, range increased, and the wipers and highbeams are great now!
Humans are terrible measuring sticks.
