@Basmitharts Honda Civic mk 9 (probably others) you cannot close individual dashboard vents, so when I have my phone hanging on the vent in the winter I cannot use these vents at all or my phone will overheat from hot air. It blows cold air in the summer however, so it's 50:50 π First world problems I guess...
@Basmitharts I thought of another dumb design. It's a hatchback with really steep slope. Because of that when you look through the rear view mirror you don't see thorough the whole rear view window. Some great engineers though you don't need heating elements on the the parts of the rear view window you don't see. You guessed it - half the window is still covered in ice and you wipers don't really like it π
