This is interesting:
Seems on the first emergency brake test the model 3 stopped in 130 feet, which is good, but in all tests thereafter the stopping distance was greatly increased.
This is highly unusual to say the least - the testers state they've never seen anything like it before.
Could it be that Tesla programmed the ABS to only brake really hard on the first attempt, so as to fool customers taking a test drive, and to brake softer thereafter in order to reduce stress on brake and suspension components?
Tesla admit it's a software problem, so the behaviour is clearly programmed in at source, by Tesla.
As ever, with everything Musk is involved with, the whole matter is very shady indeed and doesn't really make sense if thought about for more than a couple of minutes...
Edit to include:
Perhaps this is part of the reason:
I've never seen anything like it, and the top voted comment, by an obvious Tesla social media marketing consulant, is a blatant lie that has been upvoted with sockpuppet accounts - loads of people take their daily drivers to trackdays without having anything like these issues.
