"A modern F-150 isn’t a 70s F1 car made cheap by new tech. "

Yes, it pretty much is. You have to consider technology in cars is moving on two seperate/distinct paths.

1: improving manufacturing processes, materials, quality, which is lowering prices over time. Megacasting aluminum car parts is an example.

2: Adding totally new complex parts and systems that cars didn't have. This is things like airbags, antilock breaks, infotainment system, catalytic converters. This adds to the total cost.

#2 is far outpacing #1, which is why prices of cars are going up faster than inflation, wages, etc.
