> It's really hard for them to figure out when people are in cars, buses, bikes, etc. Did you ever see the artist that created "red traffic jams" on google maps by using 100 phones in a kiddy trailer?
I don't think it's got much to do with the map data being hard to figure at as much as "carrying 100 phones set to a car trip up and down the road in a hand pulled wagon for an hour" being an irrelevant thing to worry about. 100 people aren't going to be driving on top of each other with the directions accidentally set to walk very often and outside of that kind of use case the data is going to be extraordinarily accurate.
