The 4 wide will, IMO, help kill NHRA drag racing.
I put it in the same category as the confusing qualifying, the 1000ft, and the countdown.
I have no plans to pay to see this four wide stuff in person.
Again,IMO, you are getting half the show for the same money.
Consider that it takes about two minutes for a fuel car to make a pass, from start up to turn off, with the two car eliminations you see 15 pairs go down the track for 30 minutes of entertainment.
With the four car deal you get to see seven rounds for 14 minutes of entertainment. I personally find it impossible to watch four cars at a time.
I do think that the four wide will give a great boost to the nostalgia races.
