In regards to electric cars, I question where the power will come from to keep all these cars on the road. No doubt we would need many more electrical generating stations, probably of all types - nuclear, coal, gas etc. I can see electricity rates skyrocketing. The oil market has proved to be quite competitive, and international, keeping prices low. Electrical generation on the other hand, is local, unaffected by international prices.

I wonder if in the final analysis, given the losses in transmission, losses in converting and storing electric energy in batteries, wondering if there is a net benefit over gasoline combustion engines?

GG, in the oil business, gasoline specifically, and diesel, we didn't design fuel so that most cars could use it. We needed to enable ALL cars to function well. There were problems at times such as vapour pressure in sensitive cars, or octane requirement increase, or lead being eliminated and valve seat recession and problem as a result. Yes, you are right that MOST people drive, on average, something like 50 km per day. But your mileage will vary.

A car and it's energy supplies have to work in the extremes too if everyone is going to adopt the systems that are available. That's why Tesla has gone with a giant battery and superchargers in an attempt to get range without too much inconvenience. To heck with the cost in Tesla's case. Tesla buyers are not curious about costs. Regular humans are. They'll use $3 of petrol to drive to a petrol station to save $2.

Also, it's a good idea to future-proof expensive systems. When Uberized autopilot cars are swarming, Superchargers will be hopeless. Imagine 10 times as many service stations because at half an hour per fill, that's how much parking space would be needed to keep them fueled. The dead time of refueling would be unacceptable. Hence the 7SSS.

Yes, there aren't any yet. When I had the idea in 1989 of Fourier transforms to make phone ASICs work, there weren't any. In 1993 or thereabouts, a physics professor in Stanford university [Prof Lusignan] was still claiming it breached the laws of physics. But now you and everyone else use my technology constantly. It didn't exist in the 1980s and was barely going in the 1990s. It got going in the 2000s and has now taken off and is ubiquitous and accelerating.

Uberized autopilot 7SSS cars will be like that. It will take decades. But investments that don't head in the direction will NOT be wise. You won't be parking a car at home. You won't be driving a car. You probably won't own a car.

Auckland is spending $billions on a train tunnel and railway. They will just get it finished when it's obsolete and abandoned. Such is government "thinking". The public also is not too bright. Average IQ is only about 100 [and that's on a good day, when not actually drunk and passed out].

Think ahead. "Average" mileage is irrelevant.

If everyone plugged in at home to recharge their car, the flimsy wiring down the street would be overloaded and line losses would be expensive. Uberized autopilot cars will be parking somewhere else. Recharging will be at big parking facilities - probably on disused motorway lanes or other disused lanes on big roads. Autonomous cars need much less road than needed by large, dopey, low intelligence primates with their half second reaction times [when they are not asleep or drunk or ogling out the window, or doing naughty things in the car]. So Peak Roads will lead to a decline in road sizes.

With 90% reduction of total cars, a LOT of parking space will become available. Cars will do an average of 500 km per day instead of 50 km. They'll need several recharges a day. The recharge will need to be 7 seconds, not half an hour.

Motoring costs will plunge. Traffic jams gone. Road tolls and autocar pricing will mean no more traffic jams. Trips will be fast. And safe. Short car insurance companies. Tesla is already moaning about insurance prices and threaten to start their own low-priced Tesla insurance as they don't want to subsidize the barbarians.
