Some things are a disaster waiting to happen. Having a motor vehicle without a driver is one of them. Dubbed Personalised Public Transport or "PPT", people could have a bus roll up to their house that uses magnetic markers in the roads as a pathway, and an obstacle and traffic detection system. Word is the buses will only do 25mph tops, but may go up to 45mph on certain routes. Sounds kind of scary but fun, like eating grubs.
