I guess everyone is talking Of the order 80 Amps and higher without
thinking. A casual observation of cables that carry the currents are not
thick to carry such high currents and such high current handling is a
safety hazard. Also, given the fact that cars move and hence the vibration
will cause heavy sparking and damage the wiring.

The idea that disturbing a fitted cable can cause huge electric
discharges and fires is a Hollywood meme with no basis in reality.



Only the cable from
battery to the starter motor is thick as it carries a peak current of upto
400 amps At engine cranking moment but then to a fraction of a second and
not continuously!
