My 2019 Mazda CX 5 is my first car with an HUD. I really like it. As others have mentioned it is particularly useful when using the Navigation feature. I have the windshield position of mine adjusted down to where it is at the bottom of my line of sight just above the gauge cluster. That way it isn't in my face when driving but a quick glace down gives me all the data I want. It is important to get into the Settings menu when you first buy the car and choose only those features that you deem important, otherwise the display can get too "busy".
