I live in Oxford and the cab drivers hate this idea. It's going to cost them at least £460 each at time when most of them are struggling to survive. They're also convinced its about snooping on them and have all raised privacy concerns. The council has refused to say who will have access to the tapes or what protections there will be.
Most Oxford cab drivers are Asian and few can afford to live in Oxford itself and so drive in from surrounding towns. There are hordes of them demonstrating at the town hall before every council meeting but the councillors don't seem to care - whether their lack of local vote is causing that or not, I don't know. Every cab driver I've spoken to believes someone in the council is 'receiving inducements' for this - no idea if its true!
Oxford City Council is hardcore Labour / militant and seems to regard large sections of the public as the enemy. Its elected by a bunch of leftist academics who have little idea or connection about the real world. Remember it was the last Labour government that tried to introduce ID cards, 90 days detention without charge and seems to have been complicit in torture. CCTV in taxis seems like a logical development!
