Ah got it, so your solution is to uproot my entire family to optimize for this one issue. Damage is already done. Plus where would I go? Who would take an old man like myself who won't be an ROI on taxes paid before retirement?
If these tragedies you describe keep happening (as described), and the fault you identified points directly to the problems of American drivers, I find it shocking you suddenly describe it as "this one issue". Either it's as problematic as you described or it's not.
And if one believes that, e.g. self driving cars will do a lot to address it in the next decade, they especially might not want to incur the costs of the alternatives.
