It’s a 50-50. I believe it’s mostly lower hoods that improve pedestrian safety, not necessarily just shorter hoods.
European compliant cars have a bunch of requirements for pedestrian collisions, particularly trying to improve head safety - the bonnet dents downwards, rather than either the bonnet being solid or the head hitting the windscreen.
An extra seat cushion can help lift you up; my mum used to drive that way.
I assume your seat is fully up already?
