Overdrive is a racing game written by Peter Johnson for the Acorn Electron and BBC Micro and published in 1984 by Superior Software.

Points are awarded for the distance travelled as well as a bonus given at the end of each level depending on the number of computer-controlled cars that have been passed.

This can happen an infinite number of times, but will give opponents the opportunity to pass while the player slowly accelerates.

The game was hugely successful, selling almost 40,000 copies across both BBC Micro and Electron versions[2] which was exceptional for that platform.

This is probably down to the fact that it was the only 3D scrolling racing game available for the Electron for many years (with hardware limitations discouraging conversions) while the BBC version had competition from more sophisticated simulations such as Revs as well as the official Atarisoft port of Pole Position.
