Cars usually use fail-safe designs, with mechanical backup for the 
electrical system. An extreme example is the Infiniti Q50, which has 
"steer by wire":

In normal operation the steering wheel of the Infiniti Q50 is not 
mechanically connected to the car's front wheels. Input from the 
steering wheel is converted into an electrical signal. The system has 
three separate electronic controllers for safety. If all three fail, or 
electrical power is lost, an electric clutch disengages and the steering 
wheel operates mechanically.


ps: I keep an Emergency Hammer in my car, in case the electric locks 
fail: http://blog.tomw.net.au/2012/01/keyring-car-escape-tool.html
