The same way they enforce mandatory insurance coverage.

In this state(IL)even though insurance is mandatory, it's an after the fact enforcement. Now what ?

This idea shouldn't fly at the Federal level. How can the feds step on states rights ? Remember the national speed limit of 55 mph ? It wasn't a national speed limit. The feds blackmailed the states into 55mph by threatening to withhold road funds. A couple of states told them to take a hike.

I'm guessing the feds could require it on new cars, much like seat belts or catalytic converters, but they'd probably have to grandfather in old cars.
