I've always dreamed of a cab with Artillery Duel from the C64.
You know, the game with two cannons in the mountains and you have to enter the power for the shot, considering obstacles between the two cannons like mountains, trees etc. and the wind.

I thought you could have a lever on top of the controlpanel to select 1 from let's say 5 different amounts of gun powder for your shot. (similiar to the lever on Missile-X for the 3 different distances) You have to load a cannonball, maybe by rolling a trackball. And you have to adjust the angle by turning a wheel at the front of the cab. Like the ones used on the big cannons. Finally you push a big red button and the cannon fires towards your opponent.
Of course you're limited in both, cannon balls and gun powder. If you run out, you can just watch until you're destroyed by your opponent or until he ran out of gun powder or cannon balls as well. The amount of damage would then tell who won this round or it would simply be a draw and no one won.
This could be a cab with only one set of controls for alternate gameplay or with two sets so both players can play at the same time. This would be a hell of a race
