Get the speed of toy die-cast cars!

We, kids of all ages, enjoy playing with our fancy cars... We NEED to know how fast they run.

Seeing my eight year old boy playing with Hot Wheels cars, running fast on a speed lane and screaming loud, " This is the fastest car in the world! 300km/h!" I started wondering if I could make a device to measure the actual velocity of this wonderfull little cars. And a quick browsing on internet show this crazy thing called "Arduino."
