Is that actually true? I've heard of ambulances & police cars having such devices, but they were supposed to be infrared.
The last time I saw the strobe on top of a school bus active, it was when I was a passenger in one, driving down the freeway at night, and it wasn't strobing particularly fast. It's possible that our driver just forgot to turn it off, I suppose - he was that kind of guy.

School buses in my state are legally required to run the strobe when passengers are onboard.
No two strobes I have seen strobe at the same frequency. I think this traffic control story is urban legend.
