Not sure what to say....
Discussion
I don't know why we're addressing a muppets post on another platform on this one... but whatever...
On the point about EV's on wet/cold roads:
The thing being experienced is an EV's very responsive traction control. Most EV's, in most drive modes, will detect fractional levels of wheelslip and instantaneously (or very close to it) reduce torque to match the level of grip - and then repeat that calculation and adjustment every few milliseconds. The end result is near imperceptible TC that maintains the cars rate of acceleration on the very limit of what the conditions allow.
Because there's no initial wheelspin detectable to the driver, some people think their car is acting overly safe or is broken in some way. But actually, the car is providing the fastest possible acceleration each time - it's just doing so in an undramatic fashion.
EV's are great at launching, but they still have to do the job within the limit of physics

This in buckets.Doesn't matter if it's snow/ice, or a puddle... the lack of drama is impressive. Your accel slows as you hit the problem... and then ramps up again when you leave, and the only sign is your perception of accel change.

Yup, it's that. Pretty simple - you turn it off.I've never suffered this, so left it on. Some people seem to though, a bit like phantom braking.

I would have said this as well. It will effectively hold the car back if it thinks you are going to launch into something. Funny how you get used to such interventions! I hadn't even considered the Tesla might do the same.

100%.When you have a small gap and want to "throw" the car behind the one that just past, it might stop you doing that for half a second. Only had it happen pulling out of a cross road, when you push the pedal from standstill and there's a car still straight in front of you.
Never found it dangerous, but it is noticeable.
Didn't know you could turn it off, but it never really bothered me tbh.
