We've had self-driving cars and buses for a couple years now.

I question this over the long term. With regenerative braking and cooperative drafting, cars might be more efficient. And cars improve with every model year, whereas an HSR would be locked into an existing design for decades.

Name an actual self driving car model available to the public; better yet name the actual electric self driving car model available to the public. I won't even both to ask you to describe the so-called "intelligent cooperative smart car model or road system you are dreaming about.

I don't think there are any yet.

We we have been told in California that the electric grid is stressed and are to to expect brown out every summer. Renewable energy isnít up to the task yet and it may be years before it is , if ever. More nuclear is a possible solution but you run into the same NIMBY resistance to that. So electricity is generated by petrochemical power plants. Would we then be expected to build more of these plants?

Would we we need to increase taxes for both the HSR projects and build more power plants?

https://www.eia.gov/tools/faqs/faq.php?id=427&t=3

At least with EVs the customer buys the rolling stock. The customer can decide on an econobox or a luxury car. If the customer still has the option on flying would that not cut into HSR profits?
Putting 500 people in 10 train cars in a line so only the lead car/locomotive has to punch through the air and the rest follow through the 'tunnel' without the rolling resistance of tires on pavement is MUCH more energy efficient than lots of EVs driving separately down a highway with tires and no rails.

Nevertheless, EVs do get better mpg-equivalence than combustion-motorized cars, so there is a little improvement there, but still pales in comparison to buses, which are not as efficient driving separately than they would be drafting each other in close sequence as 'bus-trains,' which in turn are not as efficient as train-cars on rails.

Also, starting and stopping cause inefficiency, though regenerative braking recoups some of that energy, the way slowing down by coasting uphill allows you to recoup your energy for free by coasting down the other side of the hill.

No, son, it was her drinking that made me give up the girlfriend that bummed the cigarettes. That and she got me swerving into a ditch once.

Name a human-driven car that isn't prone to dangerous collisions. Name a sprawling city where everyone drives that doesn't waste land and cause deforestation, while making it difficult to LCF.

How is it that you can be so critical of 'dreaming' without ever being critical of the automotive dream in light of how unsustainable it has proven itself?

Oh come on now, we're back to the stupid Trolley Dilemma.

Except that Mr. Rogers would pick Trolley up off the tracks before it hurt anyone.

Is this going to devolve without Alan and Bob 2?

Yes you have a point. But more than likely she also claimed to be car free while taking Uber, Lyft, ZIP car, rental cars and a friends car. That is just what they do. You even have people pulling for self driving cars so they can be resupplied while wondering a wilderness trail. They too would bum a ride.

Glad and you got rid of her before she infected you? ;>)

There was no such thing as Uber in the 90s. We barely had a new Walmart. That one is also dead.

The same "topic" as almost every other thread on this list for the past several years - a troll or a rhetorical device for initiating P&R proselytizing, usually involving OT rants based on daydreams and conspiracy theories.

You can easily read the OP. It's the first post in the first page of the thread.

The issue is why other governments create effective (high speed) rail transportation networks but not US government(s).
