If it were so great, then why do we still have Diesel locomotives?

Most cities of a certain size have an electrified small rail network, and have for 100 years or more...Yet, if it were all that and a bag of chips, why isn't the entirety of the US or international Rail networks running on electricity?

No comments on futuristic cars/roadways from me, other than the subject reminds me of pictures in my 3rd grade Weekly Reader six or seven decades ago portraying happy commuters sipping coffee and reading the morning newspaper as their "automatic" cars followed the magic highways to work. All of this was promised by the 1980s!

Oh, well. At least they got the coffee sipping and reading parts right, albeit on cellphones!

You probably don't want to ask. It's a real third-rail kind of topic.

Especially considering most of those lines have a power line running next to them anyway.

The future is here brother: Volocopter flying taxi begins testing in Dubai this year - Business Insider

Its in Dubai and built by the Chinese.

I bet your 3rd grade Weekly Reader didn't tell you the future would be brought to you by an absolute theocratic monarchy using technology built by communist.

Electrified roads -- that's nothing new. I had a slot car racing set when I was a kid.

Not every new technology is disruptive, most are incremental. I could see where electrical charging strips might be installed on rural interstates in sunny areas, like Nevada, Arizona, or Nebraska. Solar panels along the freeway charge the strips. Battery-powered cars and trucks would get a rolling re-charge; a transponder in the vehicle sends an accounting code to the charging strips and the vehicle owner gets invoiced. All that's needed are industry standards regarding how the energy is sent and received.

I see this as very possible in the next decade or two, but not on every road and not an ICE killer.

No, this is new window dressing on the good-ol-US-boy-knowhow Moller Aircar that was on a magazine cover and promised Real Soon Now at short intervals from about 1970-2000 or so.

The guy's one talent was an ability to talk pennies off a dead man's eyes. I worked next to his "plant" and knew a couple of tech tycoons who had "loaned" him money.

Flying cars have been with us the last 60 years, and I know it has been that long, because I saw the first on at a big aviation show back then. None have gone for sale up to now.

The first production model.

A real cute one.

These certainly represent flying things - animated or not; however, I certainly wouldn't call them "cars," no more that I would call a kids "go cart" a car.

I remember reading that too. And now they are promising it by the 2020s. Don't hold your breath waiting for it to happen. When it comes to actually paying for infrastructure like that, we don't even pay enough to maintain our current infrastructure.
