Could they put one way tire puncture strips on highway off ramps?
Puncture strips don’t stop cars, as has been seen on live police shows.
They’d have to be automated (general emergency vehicle access), and have an emergency disable accessible to the general public (in case of immediate disaster/closure/wreck). For the latter you’d have to have a VERY non trivial punishment for misuse/abuse.

Sounds like a good idea. Deporting illegal aliens is also a good idea. An LWOP sentence for causing a death while driving drunk or high is also a good idea.
