Paul, you have to stop "tail gating" those trucks!
Seriously though, following too closely is most of the problem. Stay way back or go around them. I had a bra for my M100 Elan that I fit, then immediately took off and stored away, never to use. Changes the whole look, risks JBC pointed out, and fiddlely process to install kept me away. I tried selling it on the LEC forum and no one expressed interest.
