Hang on, folks - first of all, nobody forces the team to put a damaged chassis back on the track. If it's not safe to run it, put it away and try again next race. Why all the talk about buybacks (because that's exactly what using a spare chassis after wrecking the one you started eliminations with beyond repair is, a buyback) as if it's something that should be allowed? Why not allow every team to have multiple cars ready, one set up for a slick, hot track, one for the cooler first round, one for late afternoon shaded track, one for late afternoon hot and humid, and just pick the one for each round that suits track conditions?
The only problem with the current rule is that NHRA does not require the car to be completely re-teched before it runs after an accident as serious as the one we saw today. If it hits the wall hard enough to move the wall back, the chassis should not be permitted to run again until it's been properly repaired, not just a between-rounds thrash that doesn't stand a prayer of checking for and replacing damaged and bent tubing or cracked welds.
Why do most of you seem to think that replacing a crashed car during eliminations is a good idea? The cost of racing is already outrageous, that will just drive it higher. I though the idea was to find ways to control costs, not drive them out of sight.
The object of the Eddie Hill rule was to allow teams to replace a damaged car without having to withdraw and requalify the new car, so that teams that crashed on the last day of qualifications would have the same opportunity to compete in eliminations as a team that crashed on the first day of qualifying. Since NHRA no longer allows alternates, the rule makes it easier to have a full 16-car field start eliminations.
However, it has always been one of the objectives of racing to avoid destroying your car in order to finish the race. "In order to finish first, first you must finish," goes an old saying.
Actually, I wouldn't mind if they revoked the Eddie Hill rule and required teams to finish the race with the same engine block they started with in the first round of qualifying. Might slow them down, certainly would cut the cost of racing. Throwaway race cars just keep on driving the cost up and up and unlimited replacements are just that, throwaway race cars. We are already seeing throwaway engines - use one per round, if needed.
