question from squirrelmonkey

[woolymonkey]

Squirrelmonkey has LOTS of questions. This one is lasting longer than most. Any answers or comments for him?

Is it possible, either in practice or purely theoretically, to drive so fast that speed cameras can't catch you?

It partly depends on how speed cameras work, which we don't know. Do they bounce radar off the cars, or detect light coming from the cars, or what? If the car was travelling at lightspeed, would it outrun the detector beam? Or would it still be detected but impossible to photograph?

Geeky thoughts welcome. Anything with equations will be routed directly  to the maths monkeys without passing through my brain.

Well, you can confuse them by passing them at the same time as another vehicle on a single carriageway road. (The ones on dual carriageways and motorways can cope with two or more vehicles at once.) I will ask P about this, though.

Thank you. I will pass that on.

I am going to follow this thread, because now I'm curious!
