radar gun

I want one of those Hot Wheels radar guns for my own amusement. Bear in mind that it isn't limited to just working with the toy cars: it also works with bikes and such. I could even join Jay Santos' Citizens Auxiliary Patrol and warn drivers of (regular size) cars that they were over the speed limit. Plus, it measures in both MPH and KPH, and it can adjust for the size of HW cars (1/64 scale) as well as measure real speed.

Now, of course, it should be pointed out that simply by buying this product you have no arrest authority or anything.
