The lucky dog should be done away with. Take Pocono, 2.5 mile track; If you are down 1 lap and fixin' to go down 2 laps and the caution comes out, If you are the first car 1 lap down- you get almost 5 miles back. then you pit mostly by yourself after the lead lap cars pit. You can fix your car if there's something wrong. You can fill up with gas and be better than the other lead lap cars in that way. Hell, if its late in the race you can refill several times druing a long caution and maybe some of the folks in front of you can't make it to the end on fuel.
