Thinking back in the motorcycles I tested with adjustable (electronic) windshield, changing the angle or changing the height, both create a different effect in buffeting and turbulence... depending the speed, wind conditions of the day, etc. Good thing in the electronic versions is that you can notice the difference instantly while riding it as you can change those things on the fly to suit your taste/need. A different madstad windshield here for a different motorcycle discusses about adjustability in both ways.
