From the article: "So it looks like Yahoo's directions were pokey, and MSN's, near as I can figure, would have had me jumping a divider." "

The Accuracy of Online Maps 9 comments [+]

The Cartography blog compares online maps and access their accuracy. After discouraging results, it is said: "All of this suggests that local knowledge can’t be beat which is why, perhaps, TeleAtlas has initiated an online map feedback tool to elicit such knowledge from its users. How will they determine what information they receive is correct and what is chaff sown by nasty competitors? It will be interesting to watch what happens - and if Navteq picks ups on a similar approach."

  Well, any route planner is as good as the data that goes into it, and even with all the quality assurance work done by Tele Atlas, Navtech and similar suppliers, there will still be errors, or a map may be out of date. More importantly, a set of driving directions, or the instructions from an in-car navigation system is not a finished solution, but just a (very useful) tool. A lot of people don't seem to grasp this...
