Crap! Don, Bill Elliott qualified at 210 + in 1987. Don't tell me that the speeds are too high now for the drivers to react to . That's BS. The cars are so advanced (probably capable of running 260 at Daytona) and so throttled back that the drivers are so comfortable they have no fear which leads to all the blocking and wrecking and poor racing we see today. I don't care if you call it restrictor plates or tapered spacers or whatever.
If you want the drivers to respect each other you need to have a little fear in the game. Either give them full horsepower and let them go fast or take away all of the aero that makes them drive too good at 200 and make the driver hang on for all he is worth. It may sound counter intuitive but the racing could be safer (and much more entertaining) at 240 - 250 mph than it is now.
