I'm not convinced that the good old fashioned concept of buying and owning a car has a great long term future. Self driving cars are, as we're all well aware, already being tested. It is but a small and not very imaginative hop to a scenario where you dial up an energy efficient and very comfy car and it arrives at your home and takes you to your destination, then it departs to pick up the next fare. No human drivers needed so it'll mean safer roads (stop laughing at the back !

) with more energy efficient driving styles, and no large investment by you in a car that sits on your driveway or in a parking space for most of the day, no maintenance cost, no insurance cost, etc. Need a car for your holiday ? No problem, you can rent one by the week / day / month.
Future 'events' may dictate the slow demise of car ownership : there'll be a gradual whittling away of disposable income as most of the working public find that - as they now have to save like mad for their retirement (at age 75+) and pay now for the things that were once considered 'free' or already paid for* - they just can't justify the purchase and running costs of a car. Quite where this would leave the traditional car manufacturer's, I'm not sure. Their only hope would be to be the ones who run the autonomous car networks.
* - Want your bins emptying ? You'll pay per kilo. Want street lighting ? £2 per night per light. Want to play football on the recreation ground with your kids ? Just provide details of your third party liability insurance and then you can purchase a permit to play. Want the police to patrol your neighbourhood ? That's been outsourced to various private companies as the police are too busy dealing with online threats and abuse - the companies will tender for the contract to patrol your area, just fill in the details of all crimes committed in the last 10 years and they'll get back to you. And so it goes.
