if i click on the + it will take me to
where i can click on a recently viewed or enter a location and it will add it to favorites in my guide. i've never seen anything automatically added to favorites, only recently viewed.
as far as routing goes, i've been regularly doing 630 miles between massachusetts and virginia and if i just plug in the endpoints it always sends me through nyc. do that once and unless you're a masochist that will probably be the last time. so i put in stops to route me around nyc but it would be nice if they had waypoints so as to always show the estimated destination arrival time. if i could save the route i wouldn't have to reenter it every time i make the trip. add the return trip and that means i have to do it twice.
the travel times are way to low. i've seen average speeds of 70 mph calculated from the apps time and distance data. good luck with that; maybe out west but not 630 miles on basically I-95. my car gets around 500 miles on a full tank so that's only one gas stop, then throw in a couple of bathroom/food/stretching breaks, and as i pretty much drive the speed limits i'm never going to make their estimates. reasonable average mph based on my experience is 55-60 mph.
so you night ask why do i use it. 1) it's the only app i've seen that even has stops that i can use as waypoints. 2) the advance notices of trouble ahead or an exit i have to take, some from the left lane, is invaluable to stay on course. and 3) i agree with you 100% about on-the-fly rerouting to avoid an unanticipated problem.
thanks for your comments
