How do you distinguish between reckless speeding and overtaking a slow-moving vehicle by using the fast lane? What about real emergencies where you speed to get your wife to the hospital because her water just broke, she is in pain and there is no time to wait for an ambulance?
There are many variables to consider. I hope such omni-present telemetry never comes to pass. I'd rather people have more freedom than for the state to try and create a rubber-covered world where everything is safe. Heck, I'm even worried about self driving cars because I know someone with good intentions will propose we outlaw manual driving "for the greater good".
