Stuck accelerator, runaway car.
Shifter - NEUTRAL, Ignition - OFF, Brakes - apply, Problem - solved.
Stupid driver making excuses - no known solution.
No key- Only a push button that you have to hold down for 5 seconds while trying to control the car.
Shifter is not directly connected to transmission. It goes through a computer which could decide shifting conditions are unsafe for transmission and refuse your request.
Don’t forget that these are fly by wire cars. This is not your fathers car.
