Looking at it from a more parochial perspective, one area where they could make a massive difference is in getting you home from the pub. In rural areas, with negligible public transport and distances beyond an economic taxi ride, pubgoing opportunities are currently very constrained. And, even in towns and cities, while there will be some pubs that can be reached easily on foot or by public transport, there are plenty more that can’t be. Just imagine programming your automatic chariot for a night’s crawl round some otherwise hard-to-reach pubs!
Some have suggested that there will always need to be a sober, licensed driver on hand in case of emergencies, but that rather defeats the whole purpose, and how quickly could someone be expected to react anyway if they were transfixed by cat videos on Youtube? And surely one of the major benefits of driverless cars would be to enhance mobility for people such as the elderly or those with chronic illnesses who are currently unable to drive themselves.
However, no doubt the killjoys will be working hard on ways to prevent driverless cars being used in this way, saying “that’s not what they were intended for”.
