Well, that's a right-side door, viewed from the inside.
The curve of the door and window (that you can't roll down) could account for the apparent size ... you know, if this were a real pic.

But mirror is absolutely on the wrong side. Total AI glitch there.

And the door itself, being a right-side door, is not gonna work for American driving ... again, if this were a real thing and had a real road system it's intended to work for.

Fear not, folks. There's no gas line to the engine. This vehicle is going nowhere.
And how da fuq is your car gonna run on that small of a gas tank? Even after they fix the gas line, it sure won't go far.

Why is the window that small

Less window, more gas, of course.

the mirror on the wrong side

All the better to apply your makeup, of course.

It's GenAI 4D chess. Expect to see these features in the next Tesla model.
