Live for Speed is a serious racing simulator. No arcade modes, no steering aids - YOU have to do the driving. It is therefore highly recommended to drive the sim with a steering wheel, because even though you can use keyboard and/or mouse, a wheel is what you use in a real car, so a wheel should be used in a serious racing simulator. Especially when going online, where fast reactions are required.
