I am wondering why the negative terminal of a car battery is connected to the chassis. The car is insulated from ground so it doesn't seem analogous to ground in the wiring of a house.
The only thing I could think of is it allows you to jump start the car without actually connecting directly to the negative terminal, thereby minimizing the chance of a bad battery exploding.
