How else can you park? Assuming no 360* parktronic or no surround cameras. I must see just a tiny side of my car in a side mirror or else I would hit a column or a car in tight turns.
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.
