Might note that Tesla is coming with an all electric semi. Apparently multiple motors. September announcement.

And I would not be surprised to see diesel hybrids using electric drives. So in a few years this may have become a moot discussion.

^^ I don't think that would be a good idea.

Locomotives have been diesel-electric hybrids forever. Our local transit authority has been using hybrid diesel-electric Gillig buses for 15 years. Why on earth would you not want that technology in a semi? It makes for much smoother and finer control of large loads.

Even the old drivers are going to automatics. Some ways that's easier on their knees.

If you take your CDL driving test in a truck with an automatic transmission that turns in to a restriction to CMVs with only an automatic transmission.

Hybrid technology in trucks? Yes, I think it has merit. Already seeing it in municipal applications.

Most of your steel haulers and heavy equipment transport trucks imo will stay with a manual better torque for heavy oversized loads. Don't forget there are semi trucks that do allot more than move containers, that most of you see on the highway, were I live in a heavy industrial city you see semis carrying steel coils, huge 5 ton presses, and other types of heavy loads.

I deal with trucks hauling well north of 100,000 pound loads. Double trailers some combinations have 18 axles.

Your presses and loads of steel, that's cute.

These are the presses I'm talking about this is one from a gm stamping plant were i live in metro Detroit. And you see that coil of steel my brother hauled steel like that he hauled over a 100,000 lbs a load.

This is my brothers Western Star with a 18 speed manual.

No offense, but the picture is of a Kenworth. Western Stars have a big W as the hood ornament. That picture shows the letters Kenworth on the side of the hood and KW as the hood badge.

That being said, I still work part-time driving and made a run down to NC and picked up construction equipment that had to be chained down. Basically you have to check the chains a couple of times to see if anything loosened up. This run, I had to tighten them 3 times in the first couple hundred miles, then the next couple of times they were OK. I was wondering how that autonomous truck would have handled that?

Sure for a sealed container from point A to B an autonomous truck might work, but for irregular shaped loads, a conscientious person would still be needed. Or all these sensors to detect a loose chain or blowout, etc.

No, that's a Kenworth W900. But thanks for playing.

What was your old username? I remember the same line of drivel from someone who is "not a member."
