Having just had a school bus change lanes into me this morning without signaling (or apparently checking mirrors) and having only missed getting sandwiched between said bus and a guardrail due to quick braking, all I can say is you're quite possibly right.
Now I know some people who either are or have been school bus drivers, and they're all right, but the ones I see driving... sheesh.
And what's up with waiting 5 minutes with the lights on because some snowflake isn't waiting at the bus stop? I leave early just so I can beat the school buses... when I was a kid the bus would wait about 30 seconds, and if you weren't in visual range you got left. And if you were late and didn't RUN to the bus you either got left or (if the bus driver was feeling nice and there wasn't too much traffic) got yelled at.
