No answer yet to crash. Just wondering how all these electronics may go haywire and cause a crash.
The only thing you can do to guarantee that your presafe system is working to spec. is to try to crash your car. Otherwise, go to a large open parking lot, hold down the esp button to turn it off, with the window down 4 inches turn your steering wheel just slightly (5 to 10 degrees in either direction), accelerate up to 50kph [approx. 31mph], then turn the wheel as hard as you can in the same direction. If your presafe it working, you will know. Depending on the model [PreSafe/PreSafe II], you will see different things happen. The most noticeable thing would be when your seat starts to move into a more favorable position...If your presafe isn't working, you'll have to contact your insurance company soon there after.
