  1. 3:11 Please, check the ball joints for your front right wheel of the Supra. It appears to have loose ball or two in the front suspension because the wheel is moving so much relative to car body.

  2. The length of the pulse isn't the important part, the important part is how close to traction limit the whole braking sequence can go. It seemed to me that Tesla was too aggressive on snow with those tyres and locked the wheels too much. Mercedes was close to optimal on slippery conditions. The optimal slide rate would be around 5% if I remember correctly: the tyre should rotate about 5% slower at all time than freely wheeling to get maximum stopping performance. That would cause the tyre to slip nearly all the time because braking force is high enough but not slide around to allow controlling the car. If the wheel rotation totally stops during one pulse, the ABS controller is doing poor job.

  3. Even that Toyota would do fine in Winter with proper tyres. E.g. Michelin X-Ice Snow would increase the traction a lot compared to these tyres.
