Why would AI or fuzzy logic need to be provided with perfect sensors when human drivers are not? If you break 101 times out of 100, whoever rear ends you is at

Why would AI or fuzzy logic need to be provided with perfect sensors when human drivers are not? If you break 101 times out of 100, whoever rear ends you is at fault, 99 out of 100, OTOH..

Because traction control is a safety system and if it kicks in when you don't expect it it can turn a safe system into an unsafe one.

  Yes and a good driver can get you killed from good reaction time. Driving is a game of russian roulette that involves a lot of intelligences with poor senses doing random things.

    This is table stakes for TC which companies like Bosch solved and commoditized. I don't know why you're defending it.

    Yes, but you don't add extra complications to see if the drivers reaction time is 'good enough' or not, especially not since (1) this is a solved problem and (2) it is supposed to make you safer, not less safe. Tesla should simply fix this.

      Then maybe follow your manufacturers maintenance guidance and stop assuming all cars are made the same?

  Sounds like fail-safe design. It decelerates instead of spinning out of control. You’re overreacting a bit.

    Traction control can selectively apply the brake to the wheel that it thinks is spinning too fast. If the wheel isn't spinning too fast that that can throw the vehicle into a skid (the reason traction control exists is to avoid going in to a skid). So it's not just decelerating the vehicle, it's decelerating the wheel that it thinks is rotating too fast to make it match the speed of the road. When in a curve as described by the OP if the wheel is a front & driven wheel this could cause severe understeer causing the car to move further out, which will in turn cause the inboard wheels to slow down further relative to the outboard ones. This could cause a positive feedback loop. Note that if you start braking one wheel that's on a diff the other wheel will attempt to speed up.

  Had an '05 Jeep Grand Cherokee that LOVED to kick in traction control right at the critical moment of trying to make an abrupt U-turn. Like pedal down, lurch.... ummmm, think... ok, here's SOME throttle... while there's a SEMI barreling toward you... Ya learned NOT to try u-turns that might require haste.

    Oh that seriously sucks.

      My TC does the same thing. All cars after 2008 will cut throttle and apply brakes if losing traction. Turning off traction control disables this system until you press the brakes which then enables passive traction control (the car will not actively brake but will cut power) Thank Ford+Bridgestone for this
