I was taught to adjust my mirrors so that I would have to shift my head slightly in the direction of the mirror to see the side of my car in the mirror. I didn't realize this approach wasn't the "normal" way!
I do this on long drives, but always have to put it back to normal when it's time to park. It would be neat if cars would implement some sort of automatic switch between this configuration and the straight-back mode when reversing.
So you also angle the mirrors down a ton ? My old car (a VW) had an option to automatically do this on the passenger side mirror when in reverse. Not sure id want to do this manually each time though (up and down)
With manual mirrors I aim for driving and 'hope and pray' when parking.
My current car has cameras which show me the ground around it when I press a button which solves all my needs. Probably a better solution, but not on most cars from what I can tell.
