Actually, I think this would be a vast improvement to Formula 1
racing. We just declare out-of-bounds driving to be "undefined
behaviour" in the C sense and permit it to crash at run-time, and then
optimize the actual driving away. The net effect of the race is to
burn certain amounts of fuel; the cars themselves are immaterial. A
properly optimized F1 race, therefore, is a bonfire.
