My wife was driving in moderate rain on the freeway. We were going about 70mph which was the same speed as the rest of the cars. We were going around a gentle turn in the road. Then without warning, our car started to slowly spin around. My wife instantly and completely lost control. We spun almost 180 degrees, crashed into two other vehicles, and came to rest against the cement barrier. Luckily nobody was seriously hurt, but we totaled two vehicles and damaged another. If the spin had happened along a different section of road we frequently drive on, we would have slid into oncoming traffic and people could have been killed. I requested that Tesla send the full data logs of the accident. It shows that my wife released the accelerator pedal right when the spin started. In most cars, releasing the accelerator causes the car to gently slow down. But Teslas, on the other hand, do aggressive regenerative braking when the accelerator is released. So it was as if my wife had pressed the break. HERE IS THE PROBLEM: THE REGENERATIVE BRAKING SYSTEM APPLIES THE BREAKS TO THE REAR WHEELS ONLY. On dry pavement this is fine, but on a wet road, going around a turn, hitting only the rear breaks was enough to cause the back of our car to slide out from behind us. Here is more detail: 1. Our car was All Wheel Drive. But the Tesla has published that for increased efficiency, they don't actually use the front motor except during high acceleration. This means that most of the time the car is
