I feel like there's very little engineering reasons why we can't...
It's not an engineering problem. One could cut new holes in the front bumper of an old car, add forward-facing radar, tack on a display and a computer to drive it all, et voila! Now you have collision avoidance! Except even in volume, you've probably spent more than the car is worth (labor will be the killer, not hardware), or enough that the person whose economics dictate an older car can't afford the upgrade.
Lane keeping? I don't even want to think about what that retrofit would involve.
I understand your premise, but I think the missing part of the cost function here, especially when it comes to safety, is the price of a human life. The US government has actually quantified it, and I think when we account for that it’s probably worth it. Though where exactly that money would come from is a problem.
Similarly, we know certain preventative medical treatments are costly but save money for the system as a whole when universally applied, yet we still don’t do it.

I'm not sure why that needs to be the case. Open Pilot is essentially a working aftermarket kit, but they can't sell the whole kit legally, only the hardware.
