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.
Meanwhile when parking I don't need to see things more than a couple feet from my car.
