I am very cynical about AI, having experienced what happened in the 1980's. It was just the same as now, with all the hype but without the threat of AI controlled cars.
The idea of a driver-less car sounds great, until all the qualifications are spelled out - such as that these cars might be restricted to motorways, and would have to revert to manual control in other circumstances - so you can't be driven home after a boozy party, nor can you send your children somewhere alone by car, nor can you start a walk at point A and tell the car to meet you up at point B!
A real driver-less car would have to figure out whether a child (or adult) was likely to blunder into the road, whether a lorry shedding some of its load was a danger or not, understand the difference between a horse with rider, and one without (which I encountered once on a motorway), recognise the sound of some piece of debris getting stuck under the car, etc etc.
The 1980's AI hype was dominated by the idea of Logic Programming, which is hardly ever mentioned nowadays. LP was great at figuring out family relationships, but only if nobody was adopted, changed sex, or whatever! There is no steady progress towards AI - just a series of hype fuelled lurches.
