I wonder if there could be a feasible business opportunity here. Basically, launch a service to access "express routes", which are really just normal roads clogged up by people spoofing GPS on Google Maps, enabling faster travel for those subscribed to the service since they get the actual clean data. Obviously this won't work in the long term, but in the mean time you might be able to divert some users off Google Maps to an alternative you're trying to market.
