Will this work with bikes? Well, with people who aren't squids anyway? I mean, I'm wearing my helmet with a tinted visor and they're telling me they can tell it was me and not someone else? I guess if they subpoenaed the clothes they'd see it was me. I'm also assuming they're taking the picture(s) from the front of the car as you're approaching in order to get your face, plates, and speed at the same time. Bikes don't have plates on the front. What are they going to use to identify the bike's owner in the first place?
On my trip to STL last weekend they had those photo enforced areas all up and down I55. They must not have been active yet, but the signs were there when you entered a work area.
