I presume cars are made a economically as possible, so is it really the

Seems to be. When you make electronics in bulk they may well be cheaper to
the factory than high current cables and switchgear. But not, of course,
when it comes to buying replacements, if needed.

So saying, my last car was an early adopter of this idea, and the
electrics were very reliable even at getting on for 20 years old.

Just wait until the electronics are not very reliable.
