@ErickaSimone I so agree. The key to more efficient transport with lower carbon is not self driving cars, not even electric cars. It is superb public transport. That means buses and trains that are frequent, cheap (preferably free), and easily tracked by a mobile phone or similar so you know when it is arriving. It means safe, comfortable stations to wait in. It means vehicles that are accessible to disabled folk. We'll still need cars for rural etc, but far fewer.
