"Ban this dangerous weapon right now"
It's the favorite tool of serial killers. We probably have to go slowly, though, better half a loaf than none, maybe just take one slice at a time. First, regulate cars as tightly as we do guns, no purchases without a background check, no interstate sales, possession forbidden to felons, persons with mental commitments, illegal aliens, etc.. Then outlaw these particularly dangerous vehicles.
