people who turn without signaling, people who go when i ahve the right of way (like if they have a stop sign & i don't & then i have to jump on the brakes), people who leave their blinker on & never turn, people who don't let me get in their lane on the freeway even though i've been signaling & i need to get to a certain exit (i speed up, they speed up, i slow down, they slow down), when i have to turn left & theres no arrow... and the other cars keep going even when the light is yellow... and sometimes even after it turns red... so by the time i can go it's been hella red already, cars that drive hella slow in front of me, etc...
