geezers & 3 phase

Yes its good that there are some of us on here. Many geezers are really hip. I still love fast cars and my Eco-friendly cars will need to be able to pass some fuel sucking monsters on the road as a statement if nothing else. But the fuel savings is really my first priory.

I am at the point where things are being considered about an electric car. So far everything I have seen on 3 phase power supplies go with the higher voltage, like about 300 or more. Also the companies that sell the parts for them usually put the schematics up to that voltage range. Why?
From what I have learned through the years, is that the reason to raise voltage was to be able to transport electricity in smaller wires. I have also noticed that magnetism works great at low voltage so why not have 3 phase power at a more reasonable lower voltage for use in an ev where the wiring isn't of great length? I also realize that those voltages are easy to accomplish with lithium batteries but don't think those batteries are really that eco friendly.
