I drove a Triumph Spitfire for a while. Any time I took it out of town I took the state highways or country roads, because not only would that thing fit under a truck trailer, at a stoplight I could reach out and touch the bumper on most vehicles. Anything bigger than a sedan and I had to reach -up- to do it. I was only ever safe in that vehicle in the same way that motorcyclists are safe - constant vigilance and pre-planning, which I learned as a bicyclist.
I looked on IIHS for the ford F-150 and it gives a green rating for the pedestrian safety. On further inspection, this is because there is a type of automatic braking. Now, I am happy to have that system, but that doesn't have much to do with the shape of the car at all.
