Perhaps some sort of cannon? Lol I think lorries, buses and taxis will be the first lot to afford it on a mass scale. Us rural folk will just have to drive ourselvesI can understand how driverless cars might cope with urban roads with kerbs and proper lanes, but I wonder how they would cope with our rural lanes, particularly those where there is insufficient room to pass. Usually one or both cars will drive with two wheels off the road (avoiding ditches), or one will reverse up to a field entrance. How would two driverless cars cope?
