Allegedly, from an owner I used to know, that is why the last generation of front opening bubble cars all had sun roofs!Does it suffer the issue a teacher at school had? Drove into his garage right to the front. No reverse gear (*), and no room to open forward opening door.
(*) I think it was classified as a motor cycle.
Different health and safety environment back then! The idea made me laugh when I first heard it, and still does!Not for me ... worrying about low steps as it's getting difficult to manage a cross-bar. I can't image clambering out of a sunroof!
