Speeding tickets from space

As though cameras on top of every traffic light weren't bad enough already: there's now a trial run of satellites that will catch you speeding, over a several-block range, from hundreds of miles up. Hope for clouds, I guess? The SpeedSpike system is being tested at two locations in London, and works a little differently than your typical trap: cameras on the ground are assisted by satellites that are capable of calculating your average speed between two points. Which to me just means a lot of speeding, then going very, very slowly, then speeding, and so on.
This sucks for everyone. If you are speeding on the freeway at 2 in the morning and no one is around you could get a ticket.
