Probably with snapshot the best thing is to never drive your car.........
To be honest, I wonder how long it will be before these devices are mandated for all road going vehicles.
I'm a freedom loving American and love the ability to let it rip on some open back roads, but from the "save the children" perspective I'm really surprised someone hasn't proposed this as legislation. "This" being a device that senses the speed limit on the road you're on and limits your car to that speed. Tie it to some nebulous "fighting terrorism" action and you could justify Federal grant funding to buy the devices and infrastructure without cost. That would also make it possible to directly tie the road tax you pay to the mileage you actually drive instead of fuel consumed. Win-win for both sides of the political aisle, as one side gets to hammer folks with more taxes and the other side gets the obscene corporate profits that will result from having the G pay for something required in all vehicles and installed on every mile of public road. Driving is a privilege, not a right, and if you don't like it take the bus.
Of course, when this does finally get proposed the Kardashians will be doing something stupid again so America will yawn and go back to the Twitterverse.
