Driverless. It's the future don't you know.
Driverless cars are the answer, or rather will be the answer in a decade or so.
They could be owned by municipal authorities, businesses or individuals and be allocated to customers based on the nearest available and not the next in line.For that matter, the likes of Ford could decide never to sell a car ever again, but to rent them by the journey.
So, basically, a driverless taxi. Without a family and mortgage to support the cost should plummet.
The booking system would allow the vehicle to be shareable on request and thus lower the cost to the commuter even more by accepting the car will divert to get more customers who are going in your general direction.
With such a responsive and cheap service on hand, the need to own your own car would be negated. The need to fill the road and pavement outside your house with parked cars will be gone, along with the obligatory car park that consumes four fifths of retail sites and the like.
Also, as an individual car no longer has a need to keep going to the end of the day, an electric model with the most pathetic of batteries could do whatever it can manage before heading off to recharge thus making electric cars a very practical option. We could even see motorway services becoming shuttle stops as commuters continue their extended journey in a fully charged car, leaving the one that had got them thus far to recharge.
