If Ships is too slow for you then take a spin through the city of your choice with this 2D Driving Simulator for Google Maps. You’ve got a choice of driving a car, truck, bus or big rig and it’s complete with turn indicators, odometer, speedometer (your choice of units) and either maps, photos or both. Chose your city and floor it. Hours of fun.
This is a top down view automobile simulator (well, something like that) powered by Google Maps API for Flash. You can drive around the world without gas :)
