Sure, you can have ALL that and maybe more (like playing PONG while car self-drives).........yet still be constrained to traveling around big cities and always limit yourself to within range of a supercharger.
For example, my brother Model Y cannot go on a trip with us to Big Bend National Park because no supercharger around Big Bend. There is one destination charger there outside BBNP but it is in RV park...good luck finding a place there! And the super chargers are too scattered along the way...so, it would take HOURS longer just to get near there!
I see the current crop of EVs as like a big bad bull dog that is tough as hell but is on a leash and is tied down to only his yard to act tough. Sure, us piglets cannot compete in that yard.......but us piglets can roam the neighborhood and even enjoy the stroll down to the sandy beach. (And we know that if a rock hits our bottom, then we won’t have to pay $16,000+ to repair.)
Sure, we're on the cusp of a change so no surprise some things need to catch up. The next gen of EVs, with 400-600 mile range, mature charging infrastructure, it's all coming and in many parts already here. Which is why IMO, Tesla is more viable as a vacation EV than many due to its network.
While you like to focus the negative, I'll tell you what the positives are. Part of the Tesla draw is in its superlative driver conveniences. Long range travel is easy and I've done 600 miles in one day. More refreshed than I've ever been in any other car. The mental load to operate and drive a Tesla is less, significantly less, than anything else on the road. From the moment entering the car, it's already on and ready. The most aggravating drives in traffic, let the car do it. Actually, let the car do it all while you enjoy the entertainment. See a gap in traffic, you are the king of the streets so take it at will. Downhill, why would I need brakes and engine braking?
If your brother is interested in additional charging opportunities, RV parks themselves have big ol electrical stands EVs can charge from. Not just from the Supercharger installed there.
