Bottom line on this crap to sum it all up is this…
Nothing wrong with outward facing cameras.
Despite what they tell you inward ones are there to catch you and incriminate you, whether you are stupid enough to watch tv when driving or something, or more realisically where it will affect most of us, having a ■■■■ long yawn minutes before you are involved in an rta…your fault or not, because you can sure as hell bet they will pin it on you in that scenario. 
Not to mention a downright liberty and disrespect towards your professionalism (if you have any that is.
I don’t give a flying ■■■■ if the streets of the UK are awash with cameras, that does not justify putting a one in my cab.
Imo, the only ones who will disagree with my second point are the apathetic, where the injustice is lost on them, and the downright pathetic who will take what ever is dished out to them without question.
