I think the manufacturing costs for things bluetooth connectors or touch screen are usually minimal compared to the thousands of pounds of raw materials, or extensive quality assurance needed to build a car. So often these are added to luxury cars where drivers are charged a premium for them, and then later added to lower tier cars as manufacturing costs have scaled down and R&D costs have been recovered. All of this means if you want a new basic car your shit out of luck.
