A free program for Android, by VR Reality Games.

This is a fun car racing game where you get to drive and fly on the same track at the same time. Driving is pretty simple, you need to use your phone to control the car. However, flying is a bit more complicated as you need to exercise precision in controlling your vehicle. Take care not to hit a wall or building. 

There are several different levels to play. Each one has a different theme and difficulty level. If you or your child dreams of driving a flying car (at least, in the virtual world), then Car Racing Real Flying game would do the trick.
