In addition to ribbons made of pcb stuff, I guess its the fact that modern
cars use leds a lot more and hence more efficient.

The wires on 24V vehicles are thinner than them on 12V vehicles. Yes I
do know why.

Very good.

Yeahbut, I've never seen a 24 volt system on a car.

My 50 Olds had room for a second battery, but it would have been a 2nd
6-volt battery. When you only have 6 volts, you often need a secodn
battery, but I never got one. One December night it wouldn't start and
for some reason I called AAA or something, and they couldn't start it
either.

They sold a device that would rearrange the connections of the two
batteries. Never had one but I think it went from parallel for charging
to series for starting.
