It's actually solvable like a lot of things if we have time and willingness to invest in doing so. You put cameras at intersections or accept cryptographically signed unmodified dash cam footage and mail out the notice that the offending driver is a pedestrian for the next period of time starting at 3 days and progressively increasing until they are giving up driving for the next year.
If they drive during suspension the same cameras allow us to send escalating fines calculated based on their annual income in the last 12 months terminating in confiscation of their car.
Most bad drivers will get small escalating fines that aren't ruinous and stop driving like assholes. A tiny minority who are basically a menace to society will end up owing a ruinous amount of money and losing their wheels.
