What is the 2-3 hours of driving time before a break law you speak of?

Drivers must take a 30-minute break when they have driven for a period of 8 cumulative hours without at least a 30-minute interruption. The break may be satisfied by any non-driving period of 30 consecutive minutes (i.e., on-duty not driving, off-duty, sleeper berth, or any combination of these taken consecutively).

So you can find the rule that requires them to take breaks, of which 15 minutes every two hours would do.

You do realize I just said they're required to take breaks? So I'm right.

It baffles me people argue this.

Ok so you made up the 2-3 hours claim but because they take breaks, you right? BTW a 15 minute break every 2 hours would not make commercial trucking requirements. It must be a 30 minute continuous break before you get to 8 hours of driving time.

If you're not stopping every two to three hours, you are an unsafe driver. Straight up.
You are just making up safety claims that are not substantiated with facts. If this is true, how would commercial drivers be allowed to drive much longer than that?

Also, charging stops for a Tesla are 20min or less.
Supercharger stops can definitely be over 20 minutes in order to get to your destination the fastest. Even in a 3 or Y, a trip could require you to charge longer than 20 minutes but with cybertruck's larger battery, it could be even longer. Maybe 4680 changes that at some point but that's not now.

...You can't find me saying truck drivers are required to take breaks every two hours.

Why are you so upset that you're arguing with what you think I said, instead of what I actually said?

What is the point of trying to show me wrong?

Unless you're taking a route that doesn't match up with chargers, longer charging isn't faster.

I have worked on industry/gov't work groups on fatigue issues in aviation. Here is what the actual fatigue studies show.

You can't make a blanket statement or rule that works all the time. And I'm drawing a parallel between flying and driving. I can fly cross country in 5 hours and not have a fatigue issue. Conversely, I can fly from NY to FL in two hours and be fighting "micro-naps" the whole way. To draw the parallel to driving, I can and have driven to Las Vegas from home (4.5 hours) non-stop without any problems. I've also driven home from the airport (30 minutes) and I stopped at a drive through for some caffeine. Differences? Time of day, personal time of day (as related to body circadian rhythm), amount of awake time that day, quality and amount of rest over the previous nights, amount of duty previous in the day, altitude (Colorado is tough for flat-landers), and personal habits (are you an early riser, or a night owl), nutrition, hydration, health, workload, and the working conditions. And when you add to that everyone is different as to their tolerances of all the different factors, there is NO way to make a law, rule, (or statement) that is going to be a blanket working for everyone in every condition.

There are good guidelines that are generally good to follow. But they aren't hard and fast in every condition.

General rule-of-thumb for EV long-haul driving is ~10 minutes of Supercharging for every hour of driving. This is slightly more than ICE fueling, but pit stops are required either way, and more frequent stops can help battle fatigue.

I poked the numbers and here is what I get. If it got covered already I apologize I didn't want to read 14 pages of posts.

75 miles per hour at a rate of 77kw gives 1.027kwh/mile double the anticipated, more like it was towing.

16 miles was estimated to take 6% for a total of 16.432kwh

converting to 100% of the battery gives 257kwh total battery pack. Under normal driving 450-500wh/mile comes out to about 515 miles of range

Range matters in a cold climate. Period. 300+ turns into 150.

Again, everything is relative. From my experience, winter means about 25% less range. But for me, i actually get more range in the winter.. Cuz in the summer im already around 40% efficiency, driving like a bat out of hell. In the winter i have to slow down, and my efficiency actually improves..

Until someone can deliver a true long range BEV truck, I can't justify the move from ICE.
100%


I completely understand that there are people who have regular necessity for a vehicle that can do 400 miles at a go, and that may very well be each of you

but having been on the Lightning forum for quite a while, I also know there are quite a few folks who think that at first about a BEV truck, but turn out to have been wrong

to the extent it salvages your hopes for the cybertruck, two things:

first, unless your number is in the <70-90K order (and assuming Tesla holds the line that long), it may be that you take with a grain of salt what specs are offered on Nov 30 - if your number isn't pulled for another ~2 years, who knows what the CT offers by then (or if you didn't need to replace your tayotas earlier in any event)?​
second, if you don't mind me asking, what are your main reasons for feeling a ~330mi BEV truck is insufficient?​
I know the question was for someone else, but my reasons haven't changed since my reservation 4 years ago. Relatively remote, cold weather, mud, snow, hunting for a week. Can't arrive with a full charge, need enough charge to make it out to a charger.

I think you overestimate your energy use, and electricity is easier to come by than gasoline... But there's no argument there aren't use cases for being able to carry more energy.

There are alot of bad arguments, tho.
