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.
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!

carries more than that a part of start up current.
Voltage at alternator can go high enough at 150+ A to render extremely
think cable not necessary.

Again simple minded armchair engineers confuse 'breaking' with
'becoming operationally unusable'. In things like sagging floors, and in
terms of electrics.

A thick wire gives you two things: less power dissipation so it doesn't
melt and less voltage drop so it doesn't affect operations
