Most cars have a window frame and don’t need to worry about lowering the window. There are plenty of other cars that engage the window down on the lever though, so no, it’s not a technical issue. The only issue I can think of if you just open and push the door quickly then it could cause damage and the Tesla can lower the window before it opens when you use the button option.
