When the radiator fan on my Thomas C2 kicks in--it's belt-driven, not an electric like lesser vehicles--it feels like I've lost 20% of my engine power. And it kicks in every time I have to stop, so it behooves me to keep the beast rolling by braking early for red lights and letting it ease along at 15.
And then some dumb bleepity-blank-blank-bleep shoots around me and screeches to a halt at the red. So much for that plan.
When they don't do that, I can manage my speed well-enough to beat cars, even if they break the speed limit, since they stop at every light and I never get below 15-20.
Lesson: for the love of Christ, stop cutting in front of big heavy trucks/buses/etc that are slow-rolling to a red light. Do what we do, you'll get there faster. I'm behind the wheel 30 hours a week, and have been driving that exact route five days a week for five ******n months, I know what I'm doing.
