I've noted with some degree of wry humor, all the glowing reports (pun intended) about the good that radar can do. Clive Dawson, for example: <>What about other uses for unattended radar? I know of several residential neighborhoods that use huge(!) speed bumps (the kind would rip out your suspension at anything over 15 mph but are a pain at any speed) to enforce speed limits. I can imagine a system in which radar could raise physical devices which would make speeding noticeable (1-inch bumps), unpleasant (4-inch bumps), or impossible (parking-lot-style spikes?! ;-), thus allowing a smooth ride for vehicles within the speed limit.<< Consider, however: Simply running through a radar trap exposes the driver and passengers to more X-band radiation than OSHA law allows. Consider: Cops in one state (I forget which) refuse now to use the radar `guns' after being diagnosed as having cancer as a direct result of using the devices. Seems perhaps another way to achive the goals is in order. I can't allow the foregoing to go out without adding that I've always thought speed radar had far less to do with public safety than with making money for the state.
