I actually saw one of those things (the little 3 wheeled Erkel cars). No joke, some 250lb man was in it, he was in the far right lane and wanted to turn left at the light. So, while traffic is stopped at the light, he just drives between cars. Some dude in a truck got all pissed and honked his horn so the guy in the little car started yelling and throwing fingers. It was funny because the truck could have literally driven right over the fat guy. Also, the whole car was shaking side to saide as he was yelling back.
Saw that on my way home from taking the SATs, it was a nice sight to see
