The Productive Commute

One of the key reasons people want self-driving vehicles is to make their daily commute less tedious. But the possibilities go much further than simply allowing you to take your hands off the steering wheel so you can text your friends on the way to work.

At a conference in Bavaria recently, I asked the question, “Where would you most like to spend the time between getting up in the morning and arriving at the office?” For me, that place would need to have a charger for my laptop, a table, comfortable chairs, and a really good coffee machine, ideally filled with my choice of coffee beans. My coffee mug would be in the cupboard, and there would be fresh milk in the fridge.

Yes, I basically want a self-driving cafe.

The closest image I could find online was this; the front of a large and luxurious motorhome:

Now, I might not need something this large and luxurious just for my own personal commute, but you get the idea: this is nothing like my current car; it’s more like a room of my house that just happens to move around.

People often predict that autonomous vehicles will mean the end of car ownership; if you’re just a passenger in the vehicle, why not treat it like a taxi, and summon it when you need it? No doubt that will happen in some situations, if your main use for a car is the occasional trip to a restaurant, or the shopping mall, or the airport. But for a daily commute, very few people choose a taxi at present, and I think that’s unlikely to change much if the driver happens to be silicon-based instead of carbon-based.

But if we ever get something like the self-driving breakfast bar I describe above, it will, I think, be an even more personal space than the cars of today: it’ll grind my coffee beans, play my music, have the right adapter for my laptop. It may even have my choice of curtains at the windows. It will be more tailored to the various needs I have while using it, than is a traditional car, which is tailored primarily to the single task of guiding it down the road.

In short, so many more personal preferences may be involved in choosing and using such a vehicle that I think — for the purpose of commuting, at least — rumours of the death of car ownership may have been somewhat exaggerated.

Head case

Prof. Guglielmo Tamburrini posed an interesting question in a talk this afternoon. Imagine a self-driving car faced with the option of having to hit one of two motorcyclists. One is wearing a helmet, and the other isn’t. Should it aim for the helmet-wearing guy, to reduce the risk of loss of life?

Philosophers must be having a field day with this stuff. They’re being invited to comment on the latest in sexy new technologies in a way that doesn’t happen very often. (Douglas Adams fans may remember Majikthise & Vroomfondel.) Much of the ethical discussion relating to autonomous vehicles, though, boils down to variations on the Trolley Problem, and the key thing about this — the thing that makes it an interesting ethical conundrum in the first place — is that there is no right answer. If deployment of the railways had required the Trolley Problem to be solved first, we would still be using horse-drawn carts.

The question is not, ‘What should a car do in this situation?’, but ‘How do we get to a point where society is comfortable that we’ve had enough discussion about this?’ Or, more precisely, ‘How do we get to a point where a large enough fraction of society is comfortable, that a party proposing to allow such vehicles on our roads would be elected to government?’

Many technologies, historically, have first been used, and then later have had restrictions placed upon them to reduce the risks which are discovered, with experience, to be the key ones: motorcyclists needing helmets, cars needing seat-belts, pilots needing licences, smokers needing to go outside.

What I presume will happen here is that societies who are less risk-averse will go ahead with greater degrees of autonomous driving, and the more conservative nations will watch with interest until they can amass enough vicarious experience to follow in their footsteps.

I imagine, however, that in 50 years’ time, we’ll still be debating the motorcycle question raised above. By then, though, it will be even more hypothetical, since we’ll have long-since banned motorcycles.

Hiking into the future

Today I realised there was yet another reason why I want a self-driving car.

It’s for when I’m walking.

The challenge with going for a good long walk in the country is often finding a nice circular route that will bring you back to where you parked the car.

But imagine you didn’t have to do that. Imagine that you could just walk from point A to point B and the car would be waiting for you when you arrived. You could then ride home in comfort, or, perhaps, enjoy lunch from the picnic hamper in the boot before setting off for the next reunion at point C. You could do this for days.

What’s even better is that you wouldn’t need to know your destination in advance! You could wander lonely as a cloud, floating o’er hill and dale, until you spied a welcoming tavern. While enjoying a pint of their finest ale, you would summon the car, and it would be parked outside by the time you wanted to leave. (And take you home, of course, if the ale had been particularly fine…)
