@Fetidaf I all agree with that except for the general maintenance.
Outside of the engine & drivetrain there's not difference between electric, diesel, gas, hydrogen, LPG there's no difference between vehicle types.
That's one of the bullshit things regarding the push to electric vehicles. The cost of chassis, wheels, suspension, BRAKES, windscreens, door, lights,.. etc wont change. The Greenies also don't take into consideration the CO2 emissions regarding all those raw materials in a car or the production of components from those raw materials. And before you ask I used to build automated manufacturing cells for car parts in the supply chain.
If we really want to go electrical then the main push has to be in CONVERTING existing vehicles NOT replacing them.
We also need to be less concerned with trucks, power walls and mega batteries because we just don't have enough Lithium supply to do it all. We need to be looking at other batter technologies for stationary applications. Things like the Sadoway battery or the other batteries that don't use Lithium. In heavy vehicles like trucks and the giant dump trucks & diggers used in mining there's work underway in just changing the fuel over to hydrogen. Fortescue Metals in Australia is already testing that on dump trucks. Rolls Royce can supply stationary generators based based on existing diesel engines that use hydrogen as their fuel. It probably wont work for boats and ships because of the range they need. But I can see nuclear reactors taking over for the shipping industry.

@Fetidaf I don't why you think that the energy offset for a truck is a few 1000 miles.
Its little understood outside the manufacturing industries but in general your average family car consumes more energy and creates more pollution being made than it does in 20-25 years of normal driving.
I'll be honest the first time I heard that I called BS and the person telling me was actually a mechanic. He told me to FK-OFF and go look at how much goes into just making the raw steel, aluminum, plastic and glass.
Its why I say if the Greenies knew their stuff they campaign against new cars. People forget that the car industry is the biggest manufacturing industry in the world by raw materials and energy, because its doesn't just include the cars it includes all the stuff needed to make the cars. There's entire industries like industrial robots that primarily exist for car manufacturing. I know I used to program them.
Tesla's are full of metals that aren't found as much in other cars. There's a lot more copper and copper is incredibly energy intensive to refine it to where you can use it the way its used in a Tesla.
And before you ask, I have spent most of the last 20 years on mine sites. I have worked in the iron, ore, cocking coal, copper, aluminum, uranium and gold industries to name a few. One of the first mines I worked on was a copper mine that produced 99.999% pure copper. After getting it out of the ore with sulphuric acid they eventually got it into a near pure copper solution from which they electroplated it onto stainless steel sheets. That electroplating system used a lot of power.
Copper will be the next big issue in the energy transition. Like Lithium we don't produce enough. Its why people strip it out of old houses, factories and anywhere else they can.

INDUSTRIAL CONTROL SYSTEMS engineer here:
This is WHY I KNOW FSD (full self driving) is a false and misleading concept at least for the moment.
AND APOLOGIES IF THIS IS LONGISH.
FYI - My degree was in aerospace but I have spent 30+ years in industrial control systems, automation and robotics. That has included working with many sensor systems including laser scanning systems. Although I don't work with vision systems I was introduced to the basics of vision systems in 1998 and am fully aware of many of the advancements in that area.
The actual problem with FSD is the amount of information that needs to be processed.
As human beings we just don't realise how much information our visual cortex processes every second and that's because most of it is processed by our peripheral system which is NOT part of our general conscious. Its all there in our periphery and we aren't focussing on it. Our peripheral system is extraordinary at clumping things together and dismissing irrelevant clumps while alerting our conscious system of potential threats or items of interest.
For example we don't see a 100,000 leaves attached to 1,000s branches attached to a trunk connected to a root system we see a tree. We don't see several million yellowish hairs covering 4 legs a body, a tail, a head, big teeth and an even bigger set of fangs we see a lion. Out on the African savannah people don't see millions of blades of grass, 1,000s and 1,000s of antelope, wildebeests, birds, insects and other wild life. OUR BRAIN via our peripheral system filters out the noise and will latch onto that 1 lion out of all those millions and millions of items in our visual range and SCREAM "that's a threat."
Similarly when driving a car down the average suburban street we see but don't focus on the millions of leaves - we see the trees and dismiss them as NOT a threat. We see don't see all the nuts, bolts, sheets of glass, sheet metal, paint and rubber - we see parked cars and dismiss them as NOT a threat. We see the bricks, boards, windows, window frames, paint - we see houses and dismiss them as NOT a threat. BUT WE DO SEE the bouncing ball coming down a driveway and our peripheral system SCREAMS that there's a dog or a child chasing after that ball OR we'll see a flash of something else and our peripheral system will alert our conscious brain to be aware of it. Like we'll suddenly notice one of the parked cars just moved.
This is what our peripheral system does with incredible speed. It processes a staggering mass of data every second and compares it to previous seconds and then filters out all the noise. This is why certain players in team sports seem so amazing in how they can suddenly pass to another player in a way that asks "How did they see them?" The answer is they are people whose peripheral system just operates better than average and in some rare cases a lot better.
NOW TRY AND CONSIDER HOW YOU MIGHT GET A COMPUTER TO DO THAT????
Remember no 2 trees are the same, and no 2 cars are ever parked the same, and no 2 houses are the same PLUS no 2 streets are the same anywhere on the planet. There's always something different. NOW CONSIDER that the perspective (as in the visual angles) on that scene is changing every second because your car is MOVING. You now have to process the next image and compare it to previous images to pick up that movement or notice that item that gets the wider scoping part of the system to flag an item of interest to the higher level decision making part of the system.
Suddenly you will realise that the scope of the technological task to get a computer to do what the human peripheral system does is monstrous.
Once you understand the scope of the task required to to do FSD you'll quickly realise that it MIGHT BE possible for some limited situations or MIGHT be possible once we get the visual scanning systems capable of sorting through all the noise to find those few items that need a higher level of evaluation we can't even begin the task BUT RIGHT NOW we don't have those systems because if they existed we hear all about it. We'd hear about the camera that's as good or better than a human eye and we'd hear about the processor that's as good as the human peripheral system AND NOBODY is even saying they have it under development or has made "the breakthrough".
Lets also NOT forget that a bunch of car manufacturers GAVE UP on FSD about 5 years ago. Uber sold off its FSD once they, (like the car manufacturers) realised just what it would take to do the job. This is also why, with the exception of a few tiny companies desperately trying for attention (and money) have stopped trying to build self FLYING air taxis.
Sorry if this was longish but I hope you get the gist of why it might be possible in future but NOT NOW.
