I used KB for my whole first year with LFS. I tried mouse several times but found it impossible to even keep the car in a straight line.

so i tried the mouse and since then never looked back 

(well not fast anyway!)




since day 1 in LFS (using defalt mouse controls)

I can't use the mouse to drive because we have cats who like to randomly jump on me, and I don't want to end up meeting the walls when they want a turn.
Although some people say it's harder to drive on a keyboard than with a wheel, I don't think it is. You have to practice with a keyboard, just like you have to practice when you're a wheel driver.
