My link is right from the Tesla Canada site!

Walmart has ordered a whole bunch of the trucks and they want them fully autonomous capable.

[VicHockeyFan]

Walmart said that it would test five of the Tesla tsla Semis in the U.S. and another 10 in Canada. Walmart declined to comment on when it plans to test the vehicles and how it plans to do so.

Walmart wants to cut costs.  Truck drivers cost money.

[VicHockeyFan]

Consumers want to cut costs. That’s why they shop at Walmart.

Walmart is the middleman between China and the landfill...

But the trucks will still get stuck like this

But they will only need half as many since they run 24/7.

How do you run 24/7 on a claimed 800km range?

You change out the batteries in the service yard, and put them in the big "home charger".  Unpractical to do with your own car in your garage, you do not have a lift or forklift type mechanism to change them, or an extra $7,000 for the spare battery set.  You do at the truck yard.

 

Where the "sleeper" is now, that's your battery pack space.

I'm not so sure if there's a financial advantage here.

 

Those batteries are very expensive and have very short lifespans. Your average truck won't require an overhaul for 1.5 million kilometres. Those batteries will last at most 200,000 km and by that point the range will have been drastically reduced.

1.5M km with no oil change?   Seriously though, I think 1.5M is on the very high end before you need a major engine work, I think it's closer to 800k.

It's not the high end, that's about average.

 

Diesel engines, man!

No, until an overhaul/rebuild is necessary.

One of the things that gives big trucks their incredible longevity is the fact that they run all the time. That actually reduces wear on the engine components as everything is constantly lubricated.

 

And it's the same for train locomotives that move 7,000km over the span of a couple of days. They'll run for millions of kilometres before requiring an overhaul.

That's what she said.  My mechanic instructor.  Oh ya, for sure, cold starts are the worst for engines.

That's why you just leave them running sometimes, even overnight in the cold (see: Lac Megantic).  Also, sometimes when you turn the damn thing off, it'll just be a pain to get running again.  Now suddenly your 4-engine train is down to 3, and you gotta haul the dead one too boot, to the next yard.  Trust me, turning on a train is not like turning your key in your car ignition, and 99.9% of the time it works.  Every time you start up a train, there is some hope and finger crossing too.

Yes!

 

And big rigs will run their engines 24 hours a day, too. They don't get shut off unless it's absolutely necessary.
