the biggest mistake that you can do on the road is to assume that the other drivers won't make a mistake.

i've avoided so many wrecks by now, that i guess i don't even need to hold the wheel. the car will do it on it's own
I don't know if this is considered bad driving, but sometimes i guess the intention of the line change for the drivers that fail to use the turn signals, and i usually don't let them change the lanes until i'm too bored of that, or they miss the intersection or whatever
