I guess I fall into the "accident waiting to happen" category. I would be okay with it if there was an opportunity to have a practice session on Friday or Saturday, but I see little chance of that happening.
Most of the rules seem designed to keep us near our target speed. This minimizes passing and keeps things safe. This proposal is a rule that encourages going faster (well, perhaps the speed strap does that too, but at least its straight).
I'd suggest a competition where the prize goes to the car getting closest to a target speed through the Narrows. The target speed would be your class speed less 15-35mph. So the 110 class would have at 95 target. The 150 class a 115 target. Figures are examples only.
