You are wrong about ICE cars' engines not lasting that long. The US and Japanese 8-cylinder engines, specially diesel engines can easily last in excess of 300,000 miles. The odometer in my 2001 Silverado (has a 325 Vortex 8 Cylinder) shows nearly 218,000 miles, and the problem with this truck is body rust on the lower edges of the body panels, and below the doors. The engine makes a little noise on cold starts (it should be around -20 degrees F. right now), but the noise disappears within 8 seconds as the lifters pressurize with oil. No leaks of any kind, and the engine runs smooth and quite shortly after it starts. There is a long list of US and Japanese engines that have lasted over 300,000 miles.
I have never said that ICE vehicles have less moving parts than EV's. Any vehicle can last for many years and drive miles. If that was not the case, then there would not be an antique car market. If you drive an ICE automobile there are scheduled oil and filter changes, engine oil filter changes, cabin air filter changes. But once the warranty is over, I take the automobile to the mechanic only if I can't perform the maintamce myself. My wife drives her 2010 RV4 V6 less than 40 miles per week, so I replace the engine oil and filter once per year. A gallon of synthetic Mobil 1 5W-30 costs less than $30.00 at Walmart, and a Toyota oil cartridge $5.00. The cabin air filter is a little more expensive, and so the engine air filter. But since she's not driving her car in dusty roads, the engine oil filter lasts about 3-4 years. I replace the cabin air filter once per year. I believe that your EV has a cabin air filter, right?
As I mentioned before, this year (2023) is the first time I had a mechanic replacing the brake rotors and pads of my wife's 2010 RAV4. Since this car has to set of tires that are mounted on their respective wheels (one for winter, another set for the rest of the year), and that since she drives so little, all the tires are in perfect shape.
There is no way for a Cybertruck to not have steering linkage unless each wheel has an electric motor. And what do you think would happen if you turn the steering wheel (or joke) to the right or left if the motors aren't in sink (linked) with each other? Much simple wiring harnesses? Maybe using fiberoptic cables to power the motors? Or maybe telephone wire that can take the high currents that drive the motors?
Would you like to know how long steering by wire, throttle by wire, has been in use? How about the long time that high voltages have been use for electric forklifts and golf carts? A simple internet search would yield a few surprises. All the new or evolving technologies of today are great, but these things have existed for quite a lot of years (traction/stability controls and things like that, fly by wire, wire gages of numerous kings are used in the aircraft I worked past years). But you just can't take a chance to use wiring that can't handle the appropriate load capacity. That's why you have very thick wire harnesses powering an EV drive motor. You can't use 22-gauge copper wire
