We've always thought it creepy that taxi's can record what you say and do. The good news is that Infomation Commissioner agrees and says they can only record your conversations on very rare ocassions - meaning they must activate it when they're getting abuse or something.
According ot Out-Law, "It is a disproportionate invasion of individuals' privacy to constantly record the images and conversations of taxi drivers and their passengers, the UK's data protection watchdog has said.The Information Commissioner's Office (ICO) said images within taxis should only be recorded where it is "clearly justifiable" to do so, and added that it would be rare for it to be acceptable to make audio recordings in the vehicles.
"The Data Protection Act states that organisations can only collect personal data when it is fair and lawful to do so," the ICO said. "For CCTV equipment in taxis, the ICO advises that images should only be recorded where it is clearly justifiable. Audio recordings should only be made on very rare occasions, for example where there are a high number of serious incidents and where recording is triggered due to a specific threat in a taxi cab."
