> From my understanding of US laws and human biology, no one can drive 2000 miles non-stop without taking multiple breaks in tens of minutes each. In fact, Tesla Semi's range is 500 miles because it's right at the edge of how long a driver can safely drive non-stop and right before they are legally required to take a break, during which time they can charge the truck.

IIRC the same was the case back when Model S was rolled out - the range was intentionally developed to be a little above the legal limit of non-stop driving, which to me provided a pretty solid argument against range anxiety: there's hardly a way to run out of charge on a trip and be a safe and responsible driver.

There is no legal limit for non commercial drivers in the US though? Certainly it's a bad idea and impractical to drive for, say, 24 hours without stopping, but not illegal?

Guess it becomes illegal when your eye lids starts lowering ...

Fair, I checked and it turns out I must have misremembered the legality aspect. There are, however, safety recommendations that strongly urge to take a 30-45 minute break every 3-4 hours of continuous driving, and - IIRC, that was many years ago - the model S range was more than enough if you followed those recommendations and recharged during downtime.

Most, probably 40-something, states regulate it either explicitly or implicitly.

As we know from many other subjects, anything short of federal regulation is roughly equivalent to “unregulated” for the purpose of internet hand wringing.

Re:Tesla Semi, a Deep Dive by bagels on Monday December 05, 2022 @05:30AM (#33863728)
Do you have an example of it being regulated at all?
Re:Tesla Semi, a Deep Dive by dsfyu404ed on Monday December 05, 2022 @07:46AM (#33864894)
Virginia, Colorado and Nebraska prohibit more than 13hr, 12hr and 12hr (in respective order) in a 24hr period.

I can keep going...

I’ve never heard tell of this, but there it is. I wonder if it ever gets enforced.

Re:Tesla Semi, a Deep Dive by bagels on Monday December 05, 2022 @07:06PM (#33873868)
Thank you for sharing this. I wasn't aware any states had such a thing. I'm happy to be shown the evidence that some do.

I’m only allowed to drive 200 miles at a time? Do you have a source for that?

When I do cross country drives I often drive 8-12 hours in a day. I stop to fill up and eat snacks while driving.

Re:Tesla Semi, a Deep Dive by _ph_ on Monday December 05, 2022 @04:09AM (#33863199)
Typically the drivers attention drops after 2-3 hours of driving, so it is recommended to take a break then. The legal limit for truck drivers in Europe is 4.5h of driving, after which there needs to be a break of at least 45 minutes. The maximum total driving time per day is 9 hours.

While these times are of course not enforced for private driving, they are a good measure for what is safe. Yes, you can drive 5 hours or more without a break, but you need to be aware that this is risky behavior.

I don't think you can get 3 hours out of a Tesla Model 3 going 80mph in the mountains in very cold or very warm weather. But maybe I'm wrong.
Re:Tesla Semi, a Deep Dive by frumper on Monday December 05, 2022 @10:51AM (#33867196)
Well, it's hard to maintain 80mph in the mountains, it's also less likely to be very warm as you go up. A summer trip to Tahoe from where I live in the central valley is about 2.5 hours and it easily makes that. I am even close to making it home on the same charge.

My memory of driving Washington/Iahado/Montana is that holding speed wasn’t that difficult. Lots of opportunities for acceleration and deceleration. I have never driven a Tesla. Curious to know if it can handle my driving style.

Could it make it from San Diego to Anza Borrego and back?

Re:Tesla Semi, a Deep Dive by frumper on Monday December 05, 2022 @03:30PM (#33871431)
I'm more familiar with central California, but looking up the distances I'd be shocked if it didn't make it round trip easily.

I'd say the trouble with holding speed in predominately mountain roads I'm familiar with is that they tend to be filled with slower drivers.

Commercial truck drivers are subject to different rules. They used to have a bunch of problems, like taking speed and driving for ridiculous stretches. Apparently, the rules in the states are 11 hrs/day max w/ 3 hrs of rest breaks [1].

Re:Tesla Semi, a Deep Dive by nverno on Monday December 05, 2022 @04:22AM (#33863287)
My mistake, well I certainly don't remember learning anything about legal driving limits- I'd be shocked if those were laws and not some agencies guidelines.
Re:Tesla Semi, a Deep Dive by SOLAR_FIELDS on Monday December 05, 2022 @06:12AM (#33864074)
It’s actually kind of crazy that limits don’t exist as it has been demonstrated that lack of sleep is essentially equivalent to driving inebriated at a certain point. I suspect it’s only the logistics of enforcement that prevent it from happening.
Re:Tesla Semi, a Deep Dive by bombcar on Monday December 05, 2022 @08:26AM (#33865300)
There’s a saying about small planes - it’s pointless to have range on the plane that significantly exceeds the range on the pilot.

Meaning that having 12 hour of fuel is pointless when you have to stop to piss/eat every 4-6 hours anyway.
