The windshield/cowl transition is a problem area insofar as there is high pressure there--which the snow physically manipulates by being blown into that area and accumulating until the pressure differential is less than the force required to blow it away. Toyota has hit on another way to mitigate this. Here's the 2018 Camry's hood:
The 2018 Sienna:
And 2018 Prius:
That scallop at the back of the hood induces low pressure behind it. Take a look at a CFD pressure distribution map of the 2012 Prius:
That line of green at the scallop edge is lower pressure than the yellow across the rest of the hood, and the pressure at the cowl behind it isn't any higher than across the hood. It looks stupid, but it's apparently effective enough to use on multiple models.
