That’s awful. I’m sorry that happened to you. But I’m not sure I understand your argument. If one or both of these drivers were legally in the US, what would law enforcement do differently? From my reading of your situation, it sounds like you had the misfortune of twice encountering under-insured drivers, and had to deal with the consequences. How did you make the (il)logical jump from that to, “Illegal immigration harms people?” It sounds like a causal logical fallacy to me, but I’d appreciate being corrected if you think I’m wrong.

Some general problems your situation unintentionally alludes to (not perhaps in your state, but common in the south) are criminalizing the issuance of drivers licenses to undocumented people (which literally prevents them from obtaining insurance), and the fact that these people are working in the shadows and thus being underpaid (and thus not being able to pay for insurance).

The problem of under-insured drivers (estimated about 13% of all drivers) is real. Many folks have proposed ways to quantify and address the problem (e.g., [1]).
