Auto manufacturers just don't know how to do software. They don't understand it. They treat it like just another line item on the BOM: Like a bolt or a gasket. Source it from the cheapest provider, give them checkbox requirements, and then spoon it into the car on the assembly line somewhere. They don't think of it as an ecosystem to build off of, or as something to make beautiful to compete with other car makers. It's just another costly assembly that they bolt onto the car and forget about.
