I agree, not a good idea, but I would really love to hear/feel four top fuel cars at the same time.
From a spectator standpoint I can see it lodical, from the racers not a chance.
There's a concrete barrier seperating in the center, not likely (didn't say not possible) of one cars wading up all the others.
NHRA announced it won't be happening again, and the new track in Vegas the builder said he had planned to build isn't happening anymore either.
