> Does driving large military trucks count?

No because it bears next to fuck all resemblance to civilian driving. I passed my test at ASMT Leconfield when I was in REME and I was posted there so I'm fully aware of how military HGV drivers are trained. I also remember making the transition to civilian driving and realising pretty much everything I was taught other than to pass the test was worthless. I'm guessing you know what ASMT Leconfield is.

> You spend fuel accelerating tons of load, and then you wear your brakes decelerating.

Army drivers might but modern civilian trucks come with engine braking that's capable of holding a 44 tonne lorry at a set speed going down a relatively steep hill. You use that to slow down and the brakes to bring it to a final stop.

> Truckers especially worry about total cost

No we don't because we're not paying the bills. Our employers might but unless there's a fuel bonus to be had we generally don't give a shit.

> Electrics have little maintenance

Oh my sweet summer child. That may be true for a car but not a 44 tonne lorry. The suspension and steering will still be taking a hammering. It will still be required to have six weekly safety checks here in the UK.

> you mainly need to replace tires just like in a diesel truck.

Tell that to all the Tesla Model S owners from 2012-13 where 2/3 of the motors failed by 60,000 miles.

With 28 years experience of driving lorries I can say with confidence most companies in the UK are in the same position.

> Drivers need breaks for food and water.

45 minutes after no more than 4.5hrs driving. I typically drive about 300-350km in that amount of time so I could potentially be looking at having to recharge before I'd need to take a break, especially in winter or when it's a windy day as certainly with the trucks I drive now when you're towing a 450sq.ft parachute in windy weather you can see your fuel consumption increase quite significantly, as much as 25% on nights like the other night when it was 30MPH with gusts up to 60MPH..

> Do you want the trucks now

Not as they are. Too short a range, too long recharge time and too big a weight penalty. We'd have to increase the size of our fleet 20% to carry the same tonnage we do at a time when there's a shortage of truck drivers throughout much of the world, especially UK, EU and North America.

Very few lorries in the UK do that kind of work, they're usually running out of a distribution centre 50-100 miles away. Even in London the distribution centres supplying the city are on the outer edges of the M25 and can do 40-50 miles before they get to their first drop.

Edit: I like how people who have never ever set foot in a lorry feel they have the knowledge enough to downvote me.

No good for us. Even the LNG wagons we have on trial with a 400km range can only be used for a very small portion of our work.

> The charging time is said to be 9.5 hours with AC or 2.5 hours with DC.

Our lorries run day and night and very rarely do they spend even an hour parked up before they're going back out with the next driver.

The same as an ICE vehicle, once it runs out of fuel it ain't going anywhere. If the power is out for several days then the petrol station isn't going to have power to run the pumps to fuel your car. If the temperature is too low then fuel freezes, especially diesel.

> Its barely noticeable for some when you are TV viewing distance. But the further away you are, the more its noticeable, at least for me.

Sorry but that's bollocks and working backwards. The further away you are the less you can notice higher resolution and therefore higher levels of detail. A person with 20/20 vision can resolve 60 pixels per degree, which corresponds to recognizing the letter “E” on the 20/20 line of a Snellen eye chart from 20 feet away.

This chart of viewing distance vs screen size for when resolution increases become noticeable has been calculated using the above.
