Here's a solution for London traffic suggested by minicab company Addison Lee today. The press release suggests that "the AquaCab will dramatically cut east-west journey times across London during rush hour, and is expected to be popular among Addison Lee's corporate customers, many of whom need to travel regularly between central London, Canary Wharf and City Airport. It is estimated that the AquaCab will be able to link Westminster with South Quay in just nine minutes – a trip that can take up to 35 minutes by road. "
Actually I really do think we should make more of UK rivers to reduce traffic on the road. Maybe a boat would do the job though. Or a submarine.
