I'm driving a very underpowered scooter, in a residential neighborhood at night. I come to this very steep hill, and I'm going a little too slow, with an impatient car behind me. I think my speedometer reads 20, which seems fast to me, but I know it's really slow for a car. But I just go as fast as I can go, and charge up the hill, which just keeps getting steeper and steeper, until it's pretty much vertical. I can't give up now, there would be no way to stop, but I know if I just keep going I can make it. I finally burst out in a wheelie over the top of the hill, barely able to keep control of the bike.
