This is not a bug.
I also drive a Model 3, spiritedly. Of course, I’ve rotated my tires many times, on schedule, but I replace them all at the same time. It’s standard practice. I’ve never experienced OPs behavior.
The algorithm is such that there’s a limit to the amount of “slippage” it will accept before traction control engages. A difference in tire diameters, exacerbated by a hard curve, leads to more slippage than the algorithm is willing to accept. What do you think would happen if traction control was off? :)
Furthermore, there are unknowns here - OP hasn’t specified the diameter (between 2 and 8/32’s) of their old tires. They simply stated that the tires had enough tread to meet their personal standards. Clearly traction control sees the situation differently.
- jacquesm 6y agoDefinitely a bug. If tires are within spec the traction control should not trigger, it should trigger when a wheel slips, not when it is in fact having good traction.
- AndrewBissell 6y agoA bug? In a Tesla? Naaaaaaah ...
- speedgoose 6y agoIt's fine, they will update your car remotely and remove the bug. Eventually. By the end of a year. Still want one though.
- wkearney99 6y agotried driving a Taycan yet?
- speedgoose 6y agoNo, there is no Porsche Taycan to rent in my area. It seems to be a very nice car.
- foolmeonce 6y agoWhy 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..
- jacquesm 6y agoBecause 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.
- zeusk 6y agoI guess people already forgot what caused 737 MAX
- foolmeonce 6y agoYes 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.
- BoorishBears 6y agoThis is table stakes for TC which companies like Bosch solved and commoditized. I don't know why you're defending it.
- jacquesm 6y agoYes, 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.
- o-__-o 6y agoThen maybe follow your manufacturers maintenance guidance and stop assuming all cars are made the same?
- moonbug 6y agouhoh. you're going to rattle the Tesla fanbois.
- t0mas88 6y agoIt may be "within spec" for a Tesla, but other brands with traction control don't have this problem. And that is a typical issue with Tesla, they have too many software guys and too little real world automotive experience. So they'll create these kinds of problems by implementing their own things instead of going with proven existing tech. The most rampant example was the rain sensor on the early model S. They decided not to buy the same perfectly working sensor that any German car had for 10+ years at the time, no they decided to implement the rain sensor by training some image recognition on the camera that's behind the windscreen. Worst idea ever, because it meant the 100k+ euro Model S had no automatic wipers for a long time and when they got there it was worse at detecting rain than the standard sensor on a 20k euro VW Golf...
- 11thEarlOfMar 6y agoMine thinks that a chip in the windshield is a raindrop. I had to turn off automatic wipers.
- jonahrd 6y agoTo specify further: this is a problem in Teslas with autopilot 2.0+ hardware, where they switched from 1 front facing camera to 3. That left no room for the Bosch rain/light/humidity sensor, so they put developed their own light/humidity sensor, but still didn't have enough room for rain sensing hardware. The solution was left up to the autopilot team since it was assumed (wrongly) that sensing rain using a camera was easier than using specific optical sensors designed for the task. Source: I worked on the replacement TH sensor.
- londons_explore 6y agoIt is an odd design decision, since I assume a rain sensor at its core is simply an LED and a light sensor carefully arranged. Total cost of the core components: $0.03. Neither need to be physically large either. It's even more odd considering the cameras can totally also be used as light sensors (simply read back the exposure time for example). Why get rid of one unnecessary sensor without getting rid of another? I wonder if perhaps it was done to force the vision teams to become less science/research oriented and more 'we need this result now, we have angry customers waiting' based.
- m463 6y agoI believe tesla will recalibrate all this after you drive for a certain distance. Thing is - they would get complaints because the system would disable certain functions with a message during recalibration. I wonder if they have now turned the dial too far the other way.
- Dylan16807 6y agoIf they can't recalibrate in the background, that's an entirely different problem. It's not a matter of turning a dial, it's fixing a flaw.
- Dylan16807 6y agoThis is a bug. The slippage calculation should take tire size into account. Anything else gives you wrong numbers.
