am i the only one whom this annoys?

Driving along. Hear siren. Look in rearview; ambulance approaching from astern. Pull to the right and stop the car. See some other drivers do the same, but not enough, so the ambulance gets hung up in traffic.

Now, maybe it's because I was once in an ambulance that someone pulled out in front of so it couldn't get through, but there are so few things that piss me off more than this about other people on the road ...
