I would like to have been a fly on the wall at today's driver meeting..
IMO this problem could be resolved by banning the blocking. My take is if a car behind your car is faster, you have to let them go or race them. Using your car to impede the car from behind at 200 mph is a recipe for disaster.
Drivers must ask themselves which is more acceptable...Holding up another car or cars and risk tearing up a couple million dollars in equipment while putting other drivers and FANS at risk, or letting the guy go and finishing second.
I will tell all this, if the drivers don't police themselves in this issue, NASCAR will. And we will be left with a product that is unwatchable.
