There are times when I'm riding down the freeway next to an 18-wheeler, or come up to a red light with an 18-wheeler crossing the intersection perpendicularly, and I just wonder. If the trailer was raised a bit, the bike lowered, and me tucked in flat on the tank, what if I could just ride right through that intersection under the truck, or change lanes on the freeway under the trailer, kinda like in the first The Fast and the Furious movie. Of course, I'd never try it, but the scenario does play in my mind.
There was a separate incident on the freeway where I resisted squidly temptations. I merged into the freeway, and in front of me was a pack of trucks, two of which were going side by side. Traffic was pretty light, and I could simply go around em. I had a very strong temptation, though, to see if I can split between the two trucks. I even approached them like I was about to do it, but decided against it at the last second and just went around them.
