I believe the more recent firmware versions have an option to set the engagement speed for TACC.
Yup.
You can tell TACC to always engage at current speed.
Nothing to fix here except the nut behind the wheel.

But wouldn't that apply to every vehicle that uses some variant of adaptive cruise? Did reports of unintended accel increase when adaptive cruise features became available with other vehicles?People are having some problems with TACC being activated before they arrive into the problem area. If TACC is on and your going 45mph and then you turn in to your 25mph street and forget that TACC was engaged earlier of course the car will drive overspeed as soon as it can. That is what needs fixed.
We really believe computers are 100% reliable? Even if you could - it has already been proven you can hack a car and cause unintended acceleration. It is NOT always 100% user error. To think otherwise is pure ignorance and not worth even discussing further with you.
The National Highway Traffic Safety Administration said it would not grant a petition seeking a formal review of 662,000 Tesla vehicles for claims of sudden unintended acceleration.
The agency said its review of the December 2019 petition into Tesla Model S, Model X, and Model 3 vehicles found the incidents cited “were caused by pedal misapplication. NHTSA found no evidence of fault in the accelerator pedal assemblies, motor control systems, or brake systems that contributed to the cited incidents.”
After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into SUA in the subject vehicles. In every instance in which event data was available for review by ODI, the evidence shows that SUA crashes in the complaints cited by the petitioner have been caused by pedal misapplication. There is no evidence of any fault in the accelerator pedal assemblies, motor control systems, or brake systems that has contributed to any of the cited incidents. There is no evidence of a design factor contributing to increased likelihood of pedal misapplication. The theory provided of a potential electronic cause of SUA in the subject vehicles is based upon inaccurate assumptions about system design and log data.
For those that can't master good throttle control, the 'creep' option is a good alternative for those situations . I can make the car move an inch with the throttle (and in regular mode, not 'chill'), so it can be done that way; it's just a matter of getting used to it. It's good that Tesla left that option.

It's user error.
Every. Single. Time.
To be fair to OP and others responding, they have not have their logs examined yet to determine the cause. For example it could be other causes than pedal misapplication, sometimes it's not unintended acceleration, but unintended non-deceleration (expecting car to slow down but it doesn't), which feels similar (car feels like it is lurching forward), but could involve other elements (like TC, ABS, regen interacting). Example here on the Prius forums discussing this:/thread
Yeah, that sensation or the car speeding up was a common complaint about the Volt's blended brakes, when you transitioned from the blended to friction. There's a transitory moment when you don't get regen, and the car seems to speed up, when actually it's just your perception of less deceleration.To be fair to OP and others responding, they have not have their logs examined yet to determine the cause.

However, for instances of pedal misapplication, it is true most people that do that are 100% sure they did not.
OMG. gotta love lawyers.
There are ways to “Investigate this” Before bringing in the media to damage their reputation.
YES! and I am one of them, After this happened to me a couple times, I stopped using it. It's a dumb design. I couldn't believe it was trying to speed up to over 35 mph while I was doing a TIGHT right turn into our neighborhood and almost hit the sidewalk.People are having some problems with TACC being activated before they arrive into the problem area.

Being one, I still agree.
My thought is that, hopefully, when he made his appointment, Tesla did a log pull remotely and can check again that day. Not sure if that can be done but I would think so.

If I do have a SUA event, I'm sure it'll be because my foot inadvertently slipped than the car lurching forward on its own.
I have the opposite problem. I’ve gotten completely spoiled by one-pedal driving. Anytime I have to drive a gas car, I need to be consciously applying the brakes. Thankfully, decades of muscle memory kick in but my kid’s going to grow up driving nothing but EVs. He won’t have that muscle memory to fall back on. Hopefully by then, rental fleets will have purged the gas cars.
Yep. The weird thing is my younger bro, who lives nearby, always asks me to help him put in his boat; essentially, he wants me to drive his SUV to trailer his boat to the boat ramp, since he's not good at towing or backing up a trailer, or in this case a boat. He doesn't realize that I've been one-pedal driving for a couple years now, and it's totally weird for me to have to drive his SUV with boat!I have the opposite problem.

And yes ....
