Don't know if you guys remember this one, but picture this:
We are all gridded at Mugello. The race startes and all cars jump forward. One car at the very back lagged hardcore. The lag ended and the car went from 0 to 240mph in an instant.
The lag car hit the red car, launching it forward and into my car (Tan/Blue MR2) which sent me sideways where the black car (on the right) hit me again. I think 4 of us were taken out in one fell swoop.
