Re: Wing mirrors
Wing mirrors are where they are not for ergonomic reasons but for line of sight optical reasons - a tradeoff between where the driver is, where the windows are, and where you need to see.
I would assume that the final display will be across where the centre mirror now goes and will be a combination of several cameras, with some way of highlighting potential dangers. I just look up slightly as usual and I have a 180 degree view around the back of the car.
As an emergency backup, two small folding door mirrors (no need for streamlining) that normally fit within the car perimeter, and a flip down mirror to act as a conventional centre mirror.
If someone like me can see a workable solution, the thousands of very bright vehicle designers and engineers can surely come up with a better one.
