Comment	Well, "automatically brake" isn't quite right. The brakes on a Tesla are the same standard brakes you find on any car and will only engage when the brake pedal is pressed. Regenerative braking does not equal automatic braking. That statement comes from Tesla themselves. They do slow down quicker than a normal car when not accelerating though, with the effect being similar to braking with around 1/4 the braking power of a normal combustion engines car, but it's mostly down down the electric motors winding down, which is a similar enough effect to engine braking when you think about it. The brakes themselves though do not engage. The pistons only press into the brake pad when the driver presses the brake pedal like usual. The advice, apparently, for driving a Tesla in snow and ice is slightly different than I said above, but the same concept applies. Instead of the driver feathering the brakes and not ever turning the steering wheel while brakes are applied the driver in a Tesla should do the "opposite"; that is feather the accelerator and don't turn the steering while not pressing the accelerator. Brake lights coming on... Fair enough. That apparently happens whether the brakes are being pressed or not, but watching this video... Look at the front wheels. They completely lock and stop spinning. That would only happen if the driver had his foot firmly pressed on the brake pedal, which is definitely what caused the car to lose control and start skiteing sideways.
