So, why cars still use 12V electrical system

So, why cars still use 12V electrical system.

Wouldn't 48V be smaller and more efficient also it's a mature technology in telco industry.
There's literally no reason we should be stuck with it

the corvette doesn't need more weight, it's already slower

Why change something thats not broken?

Also try to get companies on board, good luck

BMW is supposed to switch to 48v, but its not easy. cars have been running on 12v for like 80 years.

Switching is gonna make a lot of mass produced parts different. Car electronics are the most expensive shit to produce. Most car companies dont even make their own window switches, they are usually made by 3rd party companies.

There is a reason older exotic cars just used existing production car headlights, and tailights assemblies. Its cheaper to make a carbon fiber body panel than it is to make taillights, and window switches.

>more efficient
what lol?

Anyway, they are already changing since cars are now iphones on wheels.

The battery lobby has congress bought and paid for.

4X the voltage means 1/4 the amps so smaller wires, switches, etc.

that doesn't mean it's more efficient.

Yes it does

no, it doesn't.
