No, as soon as we allow average devs (instead of people working on much more limited ECU software) there will be someone insisting they should put node into it, and run some part of the car on some stack that involves 3 gb of js dependencies, and will inevitably only work half the time, outside of their extremely limited testing.

Car software will only be reliable as long as it doesn't seem prestigious to write software for cars.

Furthermore, before they put cell radios in cars, you could count on the software buried deep in your car working in a consistent manner. Now with over-the-air updates, your car can suffer a software regression at any time.
