1. change lanes in busy traffic without using the indicator
2. cut to the front of a line of merging traffic
4. park so close to you that you can’t get into your car (in a parking lot)
5. box you in when parallel parking (a common offense in Washington, DC)
7. cut into your lane before there’s enough space for them
8. merge onto a freeway or highway when they’re clearly driving much slower than traffic
9. excessive and/or unnecessary blowing of the horn (unless it sounds like the General Lee’s Dixie horn from the Dukes of Hazzard)
10. following so closely, like they’re drafting in a pro race (haven’t they heard of the 2-Second rule?)
Too much terrible driving can often lead to vehicles in compromising positions. Be safe! I’m sure there’s more you could add to the list. Feel free to comment with what irks you on the roadways.
