I run my car with the suckers on the back of the plate, works fine.
Also, I would not advise people to run their car without the plates on the front, firstly because it is illegal, and secondly, because your number plate is there for identification purposes. If your car was stolen, ANPR would not be able to ping it if the thief used the motorways.
I also find that when I see cars without the numberplate on the front that I think how chavvy it seems, that the owner prefers looks over function.
Plates off at shows, and for photoshoots then fine, otherwise,
(sorry to hijack your thread) (Also hate people referring to police as 5-0 )
