Anything in your car is designed to run 11, 12, 13 Volts. Fortunately, the rest of except apparently Pinner live in a world governed by the laws of physics where a battery system cant just up and boost potential difference (Voltage).
Tow trucks probably carry external batteries in case they need to boost a 24V system. They probably can switch from a series (24V) to a parallel (12V) set up.

Reason: Mixed up my voltages...
