Swear...after my optical mouse has got one of those "fits"(*) and i've made a 90 degree turn, hit the wall, ruined my car, caused a huge crash and pissed off evertbody.
(*) By a 'fit' I mean a 'miss reading' in an my optical mouse when it thinks I move my mouse 1 meter left or right while i'm not actually moving it at all.
On one of those rare cases when my mouse does not get a fit...i play with my own made LFS car radio to change the track to something like "Eye of the tiger" which helps me to whip myself for a 1:33.xx lap time in BL1 with XFG
Cheers
