Open this Race in a Case and inside is an entire Formula One racetrack, ready for racing with no setup required. The faster you crank your hand controller, the quicker your car zips around the track, with no electricity required.
This $60 set is quite elaborate for a mere toy, with two 1:59 scale slot cars, lots of cool scenery, and lap counters to help you keep track of who's your daddy. And it all fits in a case that's about 18 inches square. Might be a good way to keep the kids occupied in the back seat while you fight traffic.
