Need to find a drive system

[BrianBarsaski]

Look, I'm making a GTA Map, but I need a drive system. With Arrow Keys, accelerate and decelerate.
Please, I need it urgently!
And if it is possible, activates the system when the unit enter to a vehicle and desactivate when get out.
I'll give you credits in my map if you help me.
If you can, with a Example map, because I'm not good at creating triggers. Thanks machines!
