Commuters will travel farther by driverless cars
Self-driving cars will be able to follow each other so closely and precisely that roads dedicated to them could carry up to five times more traffic. On such roads, traffic lights will be unnecessary. Cars will weave round each other without stopping, hugely increasing traffic flow. As cars speed up, two things will happen. First, drivers who now live 15 kilometer from work will eye homes 26 kilometer away. Nowadays commuters spend about an hour a day travelling on average. Secondly, some of the people who now take trains or buses will hop into driverless cars. After all, they will be cheaper.
