What are heights of Appenine mtns driving from Venice to Florence?

Question

One passenger is uncomfortable at great heights

Answer 1

between 800 mtrs and 1600 mtrs

Answer 2

If it is about driving and be scared of height, not big deal. It's like driving up a hill, just green forest, you won't drive on a cliff or nothing like that. Nothing scaring, i don't even believe there are any long bridges. If you meant for breathing reasons, same thing, it isn't very height.
