How do you view transit lines? It took me months to figure out that you could hover over the search box and click the blue Transit link. This is a hugely important feature to me, and it's hidden.
Just in the past few days they did finally add back the little orange peg-man as a Street View interface, which is a big improvement.
To be fair the search box is expanded by default so the transit link is on the screen when you load maps. If you click the map the search box minimizes and you would have to either click it again or hover over.
Between that, random crashiness all the time, and the lack of multiple waypoints it's virtually useless to me.
(recently I was planning a road trip with multiple waypoints and needed street view pictures of some of the locations, the new google maps was so absurdly bad for this that I had to switch back to the old interface)
edit I see they've finally brought back the street view blue outlines and they've allowed "explore" to go away without taking away Earth/Maps navigation AND multiple destinations (AT LAST). Now all I have to do is convince them to move the traffic overlay down to the same place as earth/maps so I don't have to hunt around the entire screen. It's better, but not perfect.
this thread is indicating it is doing real time rerouting
I suppose they were trying to simplify, but now I can't figure out how to send someone a pin, how to click on a pin, how to find things around a pin, etc.
I gave up and switched to Bing. First for maps, but then for everything, and it doesn't seem like I gave anything up; I guess wasn't as married to a search/map engine as I had previously thought.
I agree with other comments here, that on the phone, Apple maps is certainly "good enough".
