The new android auto map has several things that made it less user friendly. First the posted speed and your speed icons are so small that they are hard to read in a glance. You actually have to look very close at it to read them because of the small size.
Also, the reporting button is so tiny and it's black and white now which blends it to the map more and makes it less easily accessible while driving without looking. The old bigger icons were more user friendly. Even after you select to report sometging the icons are much smaller. It just takes drivers eyes off the road for more time than necessary.

Please go back to a similar style/size or make it customizable to each user so that everyone can have a better user experience.
