Where's my flying car?
I can't help wondering if the driverless car is going to be as endlessly deferred as the flying car. In both cases there are working prototypes and announcements that a production roll-out is just around the corner, but....
I'm just thinking of the level of ingenuity required to be a car commuter in Central London - knowledge of rat-runs and back doubles, judgement about which route is appropriate for the time of day and traffic conditions, knowing that this side road is the one to use when joining a main road because there's an upstream pedestrian crossing that causes breaks in the traffic and so on.
It's been a while since I lived in London, so last time I visited I used the satnav. I think it routed me through every major traffic hotspot it could find, and I arrived an hour late. At this rate, driverless cars will spend most of their lives stationary in traffic jams.
Navigation is the easy part of the driverless car requirement, but even that seems to need more work.
