We need to bring back standardization and regulation of cars. Aftermarket parts for cars has mostly collapsed because NHSTA has deregulated almost everything. Auto manufacturers have worked hard to try and stop any 2 vehicles from sharing parts. They are all bespoke, sometimes even to the model year of a car.

That's a big part of what's made it harder to maintain cars and has driven up the prices.

It should be possible, for example, to swap in a new infotainment system on any old car. It should be possible for 2 EVs from different manufacturers to swap batteries.
