I wonder when in-vehicle computers come in standard sizes and with standard ports. like 4x gb eth, 8x can, 3x hdmi, 2x usb something along such lines. just like you buy another system from another vendor for your data centre, if your usual supplier happens to have production issues. this would also simplify computer power performance updates, to dunno go from level 2 to level 3 autonomy (assuming sensors are there already). the vehicle part of the vehicle easily lasts 10-15 years. such standardized vehicle computer infrastructure would not only make automotive vendors more independent from board and soc fluctuations, it would keep the car fresh for a longer period of time, and allow for performance software after-market sales. why not? what am I missing?
