If you could choose, car, country, and certitude which would they be?

Wheelchair accessible Mercedes Sprinter / France / and I'm not sure how can I choose certitude? I don't understand what exactly that means even after googling it 🤔 can you explain? English is my second language.

Winnebago Travato 59K, Scotland and I dunno, that my son and I could be safe.

Certitude can be very lonely. Just saying.
