I wake up every morning, and think maybe by now I've seen everything. But then............

I'm not condoning this nonsense, but other than no helmet, what laws was he breaking? Here on the interstate entrance ramps all it says is, "No non motorized vehicles" and " minimum speed 40 MPH". Seems he had both of those covered.
I'm too lazy to search the incident, but maybe the pursuit began somewhere else and he ended up on the interstate? I dunno.
