The idea behind having 2 plates is you can read the plate if the car is coming toward you (speed cameras/guns). Rather than letting it run you over and trying to catch the plate details as you pop up at the back.
Eh, I, for one, am anti speed/red light camera. For variety of reasons, face your accuser, officer discretion, etc.
In both cases, the officer (or robot the uninformed citizenry gave dictatorial powers to) is going to have to catch you out-bound (unless they are psychic.)
I digress, since front plates are really only good for enhanced revenue replacement, and they ruin the clean lines of the MkVI bow, I'm not really a big fan. Got no sympathy for communities or states that cannot adequately raise revenue in an equitable manner.
And lets face it, the front plate isn't about safety, it's about raising revenue.
