Hurt by reducing regen when traction control identifies there isn't sufficient grip. BSbefore anyone gets hurt.
Ah this makes perfect sense. Is this mode on the 2021 model 3? Ive been driving recently and noticed varying degrees of regen braking on colder nights. One night I had zero regen braking. My 3 is in the service centre at the moment. I queried this "zero regen braking" episode. It was on a very chilly night minus 5 but this snow mode makes sense. Nice to have it as an option to press rather then coming on in auto fashionThe snow mode is apparently getting triggered even on the slightest slip without any snow, so people are momentarily losing regen and power at the worst possible time. For example, on occasions you can let the accelerator off and assume the regen might be enough to slow down the car but due to the silent snow mode the regen will be limited so the car might never really slow down.
Then use the friction brakes.The snow mode is apparently getting triggered even on the slightest slip without any snow, so people are momentarily losing regen and power at the worst possible time.

I never assume the car will slow down ... I can instantly feel whether it's slowing enough, in which case I press the brake pedal. The rate that a car slows down is hugely variable, even without regen, and any driver accounts for these differences without even thinking.For example, on occasions you can let the accelerator off and assume the regen might be enough to slow down the car ...
We are driving cars with power and torque that 5 years ago were unknown outside the world of pampered supercars.
Perhaps the cars should restrict power and regen as the temperature falls below 5C.
Snow mode isn't a name, it's something that people have made up. From the video above it's triggered after the car has lost traction, not just on the temperature. Temperature may be a factor, who can say, but Bjorn was only creating it by doing 0-60 on a wet surface and feeling a loss of traction first.I’m an experienced snow driver from an actually snowy country , but prior to this feature, I got a shock driving my M3 in the snow for the first time.
When gently lifting off the accelerator before cresting a hill, a slight burst of regen caused the to car immediately brake traction on the rear wheels which required some careful driving input. Ie steering into the skid etc.
Granted, our Michelin Pilot Sport tyres are rubbish in winter weather, but I definitely think having reduced regen in the snow is a good idea.
But I don’t want the car to decide when to be in ‘snow mode’ and reduce regen based on the temperature alone though. It’s frequently cold enough to snow when the road conditions are dry. That would rob drivers of regen about 9 months a year in some places.
Also driving in snow is more than just about brake feel. Something that reduces torque and acceleration like slip start is needed as well. If these features were combined it would be useful for snowy conditions.
This isn’t just another driver aid like ABS like some have suggested. Tesla’s are not advanced enough to decide when to apply a feature like this.
I’d suggest a pop up button at start up offering the use of snow mode if both the car and driver with ‘human eyes’ detects that it has snowed.
Exactly.Snow mode isn't a name, it's something that people have made up. From the video above it's triggered after the car has lost traction, not just on the temperature.

I think the clue for anyone that if your car is not gripping the road then you should be breaking and accelerating progressively, like we were taught.
