There are plenty of great driving games on a PC.
However, none of them are the arcade type games you get on a console (PGR, Gran Turismo, Forza etc)
The great PC games are true sims. They are nigh on impossible to play without a steering wheel/pedals, an analog gamepad would be OK.
Games such as GTR, GT Legends, Live For Speed, Richard Burns Rally are all excellent driving games, and their realism and accuracy are unsuppassed on any other platform.
If you want realistic games, then PC is the best platform. If you want arcadeish games, then a console is for you.
PGR/Gran Turismo/Forza are all "console sims", but they are still very arcadish compared to GTR/GTL/LFS/RBR, where you can still do reasonably well by being very "digital" with your inputs.
