The reason asked about rolling backwards is because I spun mine on the track, went through about 140 degrees of rotation, and the car rolled backwards in a different direction (fortunately not towards a wall).
I followed the rule of “if you spin, both feet in,” which is supposed to lockup the wheels, so that the car just slides in the direction you were going (according to Newton). I’ve done this a handful of times in other cars with the expected results. But this time it didn’t. Instead, I concluded that the antilock brakes tried to keep the tires rolling, EVEN WHEN GOING BACKWARDS. Thus, when the wheels started rolling, The ABS caused it to shoot off in the direction the car was pointed at that time.
Anyone else had that experience with a car with ABS?
