A $20k American-made electric pickup with no paint, no stereo, no screen

Why not make a physical connection (power/network) and define a form factor for entertainment system with or without screen and speakers and let other companies design something to fit the space available. I don't understand why no one does this instead of selling cars full of crappy software that can't be upgraded.

That's what cars always used to have. Made them easily stealable though.
