I noticed this tag on a particle accelerator and it cracked me up, because it's right.

No, it isn't. The speed of light is certainly more than 299792458 km/h.

The particular accelerator itself is fairly stationary of course, so surely the tag should be particle:maxspeed=1079252850?

maxspeed should be fine. Otherwise we’d have to slap motor_vehicle:maxspeed on everything.
But I get the feeling this way also needs a minspeed. Wouldn’t want an ion to get stuck behind a Sunday driver.
