Some of them have pressure limiters, but I'm too scared to test their effectiveness.

When I was in high school, I went to the local gas station to fill up my bike tires. This was Manhattan, and gas stations are rare. This one is indoors, like a cave. I blew my tire, and the explosion in the cave-like space was louder than usual. The owner told me never to come back. This was before coin-operated pressure-limiting compressors.
