I speed on highways... if I'm sure it's not a cop-trap zone, but since I grew up in the city, where there's little room for idiocy, I don't take chances. Lots of idiots-with-legs will dart out in the middle of the street out of nowhere to beg me to mow them down, I've had cars in the same direction to my left suddenly take U-turns, cutting right in front of me as soon as the light turned green... FUCKTASTIC MORONS, I WISH MANSLAUGHTER WAS LEGAL SO THAT I COULD RAM YOU RIGHT IN THROUGH YOUR FLIMSY FUCKING DOOR. YOU'D DIE FIRST, YES YOU WOULD. (this happened yesterday, so I'm still a little testy over that.). I've had to find a way to get around cars who were stopped on railroad tracks TO TALK ON THE PHONE (presumably making their final goodbyes)...........cars blocking tight roads, people leaving turn signals on, people not understanding right of way...
So, I'm careful myself, and I'm a defensive driver, but that doesn't mean I stay calm. I remember I fucked up my horn once because I lay it on so hard. Had to get it fixed. Another time, at a red light, I threw a french fry at a bicyclist who had been acting like an arrogant ass and hogging the road when there was a bike lane right there. (He wasn't heeding my relentless horn use, so I decided to send him the message literally.)
