I'm certain my totalled '14 had 25% all around. I found that too dark for a lot of my urban areas, much less my rural roads.
I can't count the number of times a family with stroller would come from no where to cross at the intersection where I was going to make a RH turn. When I do the front windows on my '17 (currently has nothing) they will be 32%.
I'd rather be a little warm than hitting kids.
