What a waste of money. Now I am not a Luddite. The last 10 years before I retired I worked in Design and innovation in IT Telecoms. Driverless cars are way off being fit for purpose. As a former DoT ADI I never ceased to be amazed at the human brain's abilities when it came to managing the complexities and decision making requirements of what seems to be a simple task but in reality is highly complex i.e. driving a car in traffic. I was even more amazed though, at the human brain's ability to come up with new and ingenious way to 'cock it up'. In the future we no doubt WILL have autonomous vehicles but mixing humans and self drriving vehicles will never work IMO. Even now they require someone to be in the driving seat to 'take over' in certain situations. Now I don't know about you but that, to me, is tantamount to sitting next to a learner driver requiring concentration whilever the vehicle is moving to be able to 'step in' if things start to go wrong. So you might as well be driving yourself as it you cannot relax. In fact I am more relaxed as a driver than as a passenger. So if you cannot fully trust a machine, what is the point. Which bring me to the law... Currently, even if the vehicle is parked, if ignition keys are present the human in the vehicle is the 'driver' and deemed to be in control of the vehicle (back (people over the limit who get into back seat to sleep it off can be convicted of being Drunk in Charge as they are legally responsible. So if a driverless car hits another when you are in the driver's seat or not who is responsible? The law needs clarifying. If you hit a driverless car, how do you argue fault against a team of barristers representing a vehicle manufacturer in denial that their system is fallible. Things like build up of snow,road dirt rock salt etc blocking sensors on a vehicle will impact reliability. AI has a long long way to go before it can use intuition and cover an almost infinite combination of factors making up the driving conditions at any given moment. Anyone who points out that reaction times of machines are faster than humans knows little about driving. Anticipation and experience negates the need for fast reactions in almost all circumstances hence why older drivers have a far lower accident rate than young ones. Rant over.
