I agree with JINGLE..... putting car in neutral and applying brake or PARKING brake slowly will also stop you. I have a friend who owns one of those cars that COULD accelerate on its own.... I had her practice shifting from DRIVE to NEUTRAL quite a few times while the car was moving until she was confident in doing so.... Lots of new cars don't have parking brakes like the older cars... Hopefully, she will NEVER have to use this new skill but in case she does-she is ready and will be calm....
