Makes overtaking a far more difficult task
It's fine on motorways but it makes a noticeable difference to visibility on B roads.
Depends on the car, no? I've never once had trouble overtaking on French N-roads in a right hooker. I didn't have any trouble on UK B-roads in dad's old Barchetta. I haven't really tried it in la Citroen (only the occasional dawdling tractor) but I suspect that it's more than doable if required.
Something like the V6 Alfa that I linked is going to have more than enough punch to get around stuff quick if called upon. And the glasshouse is relatively untroubled by pillars and padding and airbag covers so you can see out of it easily even from the other side of the car.
