I drive a crossover and I'm not sure where you get this idea from - let alone it being the issue. In can see much better out of my crossover than my sedan because I have a higher seating position and a smaller engine bay to look over. Height would really only be an issue in a parking lot if a child was hiding in front of a car.
I would disagree that its limited to children as a quick look right and then left might mean that much less of the person is visible and could possibly not catch your eye as you drive forward.

How many accident actually stem from this. Even your own disclaimer has nothing to do with hood radius. That car that almost hit you was well out of "hood range" when he started to turn.
Likely, it was either a failure to check the corner or you where in his A-pillar blindspot. Every single car in the world has an A-pillar blindspot. In my experience, the A-pillar blindspot is worse on smaller cars because it's closer to the driver and blocks more of his/her vision.
Also, children are important too and if one gets in front of you pulling up on a driveway using a modern SUV could be a recipe for disaster.
