On the subject of driving: I’ve noticed that bad male and female drivers show different bad habits. For example, say a driver misses a turn. If the bad driver is male, he’ll probably curse a blue streak, drive too quickly and recklessly to the next street, and backtrack. If the bad driver is female (again, this is just my observation, so don’t get too pissed), she’ll probably make an illegal U-turn in the middle of the street and go back to make her turn, seemingly expecting others to look out for her.
Anyone else make a similar, or even opposite, observation?
Hmmm…probably a combo. I’d look to make the illegal u-turn while cursing a blue streak. My wife would keep going in the wrong direction until she came up with a new plan.
