Sorry just saw this. Frameless windows.

You’d need some carve out for electric vehicles, they are super heavy compared to a gas car of the same size. (Assuming you want to encourage electric over gas)

They are not hidden, I proactively tell new passengers to use the button not the emergency pull handle. If you use the emergency release the window doesn’t drop and can mess up the window trim. I learned to warn people after the first 3 passengers pulled the handle automatically instead of pressing the button marked ‘door’.
