Hmm perhaps the technology does hold a lot of risk for motorists and freedom.

Enter stage left motorway/major road toll booths. Double barriers. Ride past the first and it "traps" you. Wait for the second barrier to go up before you can ride off. Each time your speed over a section, insurance, MOT and tax records are checked. You cunts better hope I never become Chief Technologist for the DOT.
