The crap I see every day on the road just blows my mind. But, driving a car into the water because Mr Garmin says to is at the top of the list.

South I-5 on the ship canal bridge. People will miss the exit to 520 (now they are in the fast/left lane still on I-5) and stop. I've seen the reverse lights on a car or two thinking they're going to back up and take the exit. All the while I'm staring in my rear view wondering how many cars behind me are going to slam each other. It's not that hard people. Keep going to the next exit and turn around.....
