Scrambled eggs? Wear a damn seat belt.
Re: windshield- it's also 1/4 of the car away from the occupant, whose seating position puts them well even with smaller mid size cars. Remember, properly seated in a vehicle, you should be comfortable, but nearly straight (i think it's no more than 10° reclined), with arms mostly extended, elbows slightly bent, at or under shoulder height, but not below the pecs major.
That puts the occupant at about half way back the vehicle, with the seat being nearly aligned with the B-Pillar.
Oh, look! There's an occupant in Neil's image, portraying what I just noted.
See how there's almost no way for the occupant to make contact with the windshield? Likewise, something attached to an SUV's backside isn't likely to make contact with said occupant.
