While insect population decline seems the primary cause, windshields are also more sloped and aerodynamic now. I suspect more bugs bounce off these instead of being splattered. My one data point is that on a 2-hour rural drive with a friend my 90s SUV’s windshield and front bumper splattered a lot of bugs. While my friend’s sleeker more modern car with a sloped windshield had barely any.
