7. Don't know if this is what you want, but I was watching NASCAR this past Saturday night and they have the electronic finish line which they didn't have years ago. This past race was either the closest or next to closest they've ever had and it was amazing to see how close those two cars were to the finish line. Without this technology you may not have been able to determine who actually won the race. Or at least you would have had one driver mad thinking that he was the winner.
