Lately, it's like the goalposts are on wheels.

I see hybrids as an interim step to full electric. If I may ask, what's your 0-60 with a full load and % grade at 65mph?

They will only penetrate a niche in a very small area of the country.

20 years from now, who knows but in the next 10 years I expect less to change than you think.
If 'platoon' driving gets the go-ahead,I think it will be an economic game-changer,even if nothing else is done to the rigs.
There is serious fuel savings,regardless of motive power source,making 'autonomous' capability very attractive in a life-cycle-cost analysis.

I have my reservations about platooning. May work for mega-carriers. Everyone else who appears to be running same roads, isn't. There's an awful lot to work out in re dispatch. M

BNSF, UP and other roads have a hard enough time even today.

We've had cross-country freight-cargo "platooning" since the late 1800's...called trains. And, pounds-per-mile-per-unit fuel, they beat everything else (planes, trucks, boats).

Cost accountants may make an irresistible 'profits' case to fleet owners,with respect to this low-hanging fruit.
The DOE might even create incentives for unassociated parties to link up for national fuel savings.Like a reversed depletion allowance.

It works for NASCAR and they are competitors.

According to Elon Musk's figures, from the presentation on Friday, a platoon of his trucks will be able to transport goods even cheaper than a train.

The UK governments has announced trials of platooning on British roads, starting next year.

The one untested (AFAIK) potential gotcha of platooning or 'training' of road vehicles is how well they handle a sudden problem like the lead vehicle coming to a sudden stop due to running into a vehicle that cuts over and hits it or one that hits it head on.

How many of the closely following vehicles will crash before the software can bring them to a stop?

So, "platooning" vehicles will commandeer the national roadways while private citizens are pushed onto the back roads to get across the country?

Gooberment OF the people, but roadways FOR the BUSINESSES only?

Platooning autonomously has been in test many years.

When one vehicle crashes they pretty much all do unless the speed drop is within the braking capabilities of the vehicles .

That said they all brake at the same time so it’s less likely all crash and the damage is less then if it was human drivers, but in a head on scenario a lot of damage is still not avoidable.
