Today Rearview Mirror Gives you GPS Directions

Today automakers are widely using rearview mirrors as backup cameras. Recently MirrorPilot has given a very promising idea which suggests integrating a GPS system into left-hand corner of rear view mirror.
The problem of placement GPS is very burning now. Some automakers prefer place it on the dash, other attach it to the windshield. The last variant is considered to be wiser as the dash looks cleaner and there is enough room for other gadgets.

However the question is whether these GPSs are safe enough. Just imagine that you must look at the same time at the mirror and at the road ahead. It is rather difficult for a driver not only try to read a 2.2 inch screen on the mirror but examine it very carefully to find out the way he or she needs. It is quite possible to swerve into another lane or miss some important road information.
The price of this GPS is $1,025. However, it is obviously very high and it should be reduce to make a device popular with drivers in Europe and in the USA.
