@flo, did you look at the link I posted? The bus doesn’t even have a driver’s seat. It does have a chaperone sitting on the bus who can press an emergency stop button, but that doesn’t qualify as ‘driving’ or taking over the driving.
“Known as the RAC Intellibus, it is driverless, without a driver’s seat, but there will be a “chaperone” aboard “in the unlikely event that an incident happens and the bus control has to be overridden”, said Anne Still of the RACWA.
“Both the chaperone and passengers will have access to two stop buttons. It will stop immediately,” Ms Still said.”.
I imagine this is the future for public transport where there is a regular route.
