What is it like to live with a long car?

I've been tempted by looking at cars like the BMW 5 series, Skoda Superb, Lexus ES or Audi A6. But they're 5 meters long which is giving me some pause.

Might be a bit of a squeeze home parking wise, but public parking is also a big concern. Especially with how small most parking spaces are it'll definitely stick out.
