Speed is subjective, I always feel faster if I've just passed a few cars or a real looker. Grabbing the lead of a rush hour pack of cars on a timed arterial always makes me feel like I'm breaking the tape at a race.
Checking and topping off my tire pressure always gives me a psychological and actual speedboost versus just hopping on and riding.
And riding the painted stripe always makes my bike feel faster versus unpainted roadway.
