You're missing his point, which is not the lack of gas, although the main sources we use now will dry up at some point.

It's that in 20 years allowing cars to drive us around might be mandatory so you won't be allowed to drive your car on streets.

I won't be surprised if it happens.

And I would think that a world with sufficiently cheap solar generated electricity will go to hydrogen as the fuel for mobile usage. I suppose you could rig a four cycle engine for hydrogen but it would require a good bit of retrofit.

and of course once the automatons get going you ain't gonna allow random humans to screw it up.

None of that matters to me, I'm still driving myself irregardless.

I saw a blurb about some people who are developing a road base that generates electricity from sunlight. It is in the testing phase now. I wish I had seen more of the story. Perhaps Google.

Edit: How 'Solar Roadways' plans to create smart roads to produce clean energy and save lives and money - TechRepublic
Glass tiles covering embedded solar cells, LEDs and circuitry. Pie in the sky I think. Maybe in a parking lot.

Has all of the fun problems. Connectors for example...if you actually want to run stuff at night or even think about heating the road you are talking big buss bars underneath...driven by what power source...

I would think heads up displays showing this stuff to the driver are more likely.

Hopefully the autonomous vehicles get here before that all happens.

It's not the vehicle alone which needs to be modified; most of the problems lie within the highway network, which is probably far too large to encapsulate within a single unit of software.

To cite one small, but far-from-rare example, there is a curve not far from my home on PA route 339 (designated a state highway, but not heavily trafficked -- perhaps 500 vehicles daily, and very few trucks) which involves two subtle turns, a very short straight stretch, and two changes of gradient. Both locals and visitors (usually the latter) have been fooled and lost control for years, although speeds are slow by necessity, and injuries rare.

Any "self-driving" system is going to have to incorporate hundreds, probably thousands of such hazards.

The substance of the threat likely varies, depending on whether one is driving a Chevy Aveo, Cadillac Escalade, or a 1-ton pickup.

And also whether the driver is a 140-lb adult, or carrying three passengers who add another 450-600 lbs.

This is why I remain convinced that the implementation of auto-drive system, while increasingly feasible under closely-controlled conditions, will have to be done incrementally, and that cost considerations will limit it only to the most heavily-used portions of the highway system. It's not going to be adaptable to getting Gramps and Gran to the doctor for a very long time -- if ever.

Computers can already do thousands of calculations per second. This will be no issue for them at all.

Now Nissan says they should have driverless cars by 2018. That is only 4 years away!

This is from HNGN:

The head of Nissan-Renault alliance, Carlos Ghosn revealed that driverless cars could be on road as early as 2018, provided there is appropriate legislation.

The key phrase.
