I don't think real police are trying to type license plates into a computer while pursuing suspects or tailing a vehicle. They just use the radio unless their laptops have voice recognition.
If the typing plates in thing is permanent, hopefully there will be a way to kill keypresses registering in the background. Currently, if you type a plate in with an F, you get out of the car, and other types of weird stuff.
Absurd and reflects the same findings Sam posted. On another note I have a lot of problems with your forums. Just trying to view threads it times out 99% of the time and comes back with some cryptic error. Just thought you might like to know.
