What an excellent feature for the rearview mirror I must say. It really helps with having trucks behind you or cars with miss-aligned HID or aftermarket HID without auto-leveler at night time. I have seen this work well on a beemer a couple of years back. Ahhh, another benefit of window tint (LOL).

 

i'd trade in auto dimming mirros for...
tilting side mirrors when in reverse.
why the heck cant this be standard?

 

If you have autodimming mirrors, you have tilting mirrors. Put the L-R mirror rocker switch in the L or R postion (ie, not middle) before you put the car in reverse.

But I agree this should be std.
