Dirt experience when I was a kid saved my dumb @ss when I got back on a bike after 11 years of not riding (long story). When I got my first bike after 11 years, I got a tiny (200 cc) Honda streetbike, with super skinny tires, drum brakes, you know the drill... Anyhow, got caught in a rainstorm, pulling up the the stoplight, downshifting, back tire locked up, started to come around... many years old experience kicked in automatically, I clutched, rolled the throttle on and let the clutch out until the back tire grabbed and dropped back into line and braked as gently as possible to a stop at the light. To make a short story long, Dirt experience saved me from a spill at 35 mph, and I personally believe that dirt experience is invaluable.
