You old guys crack me up. “It was way better when I was a kid.” Right, and there hasn’t been a decent rock band since the Beatles, either.
My personal experience with rough driving is that it’s not as black-and-white as you think. “I’ll just punt this guy” often turns into “crap, I didn’t punt him and now I lost a ton of momentum by hitting him and there he goes off into the distance.” 90% of the successful contact i see is on the side pods, while wedging your way inside to pass on a tight corner.
The current bumper system works fine. Agree that stricter enforcement of the rules would go a long way. Some of the contact is absurdly blatant and nothing is done.
