That doesn't mean everything scales linearly.

Trucks are also way less aerodynamic than a fish faced Tesla.

Where?

Europe would need an all-new rail system and it still wouldn't service the continent as well as trucks combined with ships can.

I really hope you realize that Europe's cargo infrastructure relies almost completely on trucking. There is absolutely no way it is possible to make the switch to trains at this point.

I seriously doubt solar panels would generate a meaningful amount of range. You have to remember, that if you put solar panels on, now you just increased the weight of an already heavy vehicle. Solar panels on top of a trailer would also only generate 100% capacity at noon in the middle of summer near the equator. Any other time they would generate a significant amount less. Now you also have to clean the panels regularly and they have to be replaced as they wear out or break.

Solar panels on moving vehicles is just silly. Absolutely not worth it on anything other than a bicycle to charge your phone.

Try loading up that Model S to capacity and see what the range becomes.

EVs are terrible at carrying cargo, especially if you tow something.

And this is the niche these trucks will fill. Urban centres are heading towards a complete fossil-fuel ban. That means these short range EV trucks could be the only heavy vehicles allowed inside major cities in the future.

If nothing else, it will be good for air quality.
