In most of Europe, the prices of Model 3's match pretty well those of the Polestar 2. The difference in build quality between those two is night and day. The Tesla feels like a Chrysler/Dodge Neon in comparison, with leather being the only concession whatsoever to niceness.
The fact that in Europe somehow they're "premium" and not budget cars within their category blows my mind.
I checked the website it's actually $45k sticker price in the US.
The $30k price is with the $1k discount mentioned plus the "Include est. incentives of $7,500 and 5-year gas savings of $6,000" check box the Tesla site has.
I have many objections to Musk and Tesla, but I bought a used Model 3 before learning about all the insanity. The doors are designed to open with power, it's true; this is because they were built without a top frame, apparently to reduce weight, so the powered button lowers the window as the door opens to avoid damaging the glass.
However, there is an emergency lever (that would be easy to miss for sure) that just mechanically opens the door with no need for power. I have used this once to make sure it works and can confirm it exists and functions. Presumably, this is true of the Model Y as well; I can't imagine that a vehicle could pass any kind of inspection if there were no way to get out without power.
The frameless window has nothing to do with the decision. Cars with mechanical door handles have been retracting the window on opening longer than Teslas been making cars.
