Go ahead, opt in to the new Bing Maps Web site and check out the changes. Bing Maps has shifted to a card-based format, so you'll receive plenty of information about a particular restaurant or named destination, before you even think to start asking for directions. You can get a quick description, phone number, address, and even reviews from Yelp and TripAdvisor. Google Maps offers the same collection of information, but organized slightly differently.
With the new preview, Bing's navigation feature offers estimated drive times and routes for the future, so you can know, for instance, how much time you should budget for a drive to the airport at rush hour. The card format allows you to examine and chart routes between a number of different destinations all on the same page, without a lot of back-and-forth among webpages.
I spent a few minutes this morning comparing Google Maps and Bing Maps and noticed a couple of key differences. Bing Maps is quite proud of a feature called "Along the Route," where you can highlight restaurants, gas stations, and other services that appear as you travel--great additions for a road trip. However, Bing de-emphasizes a critical piece of information that Google places front and center, especially in its mobile application: the hours of operation, and whether the destination in question is open at the moment. (The hours are there, but Bing oddly places them in the portion of the card where its street-level "Streetside" view is shown, rather than the general information.)
Another shortcoming is more glaring: Bing has updated its desktop app, but more and more people navigate using their phones. Microsoft promises a similar preview update for its mobile platforms, which is where its real impact will be felt.
Why this matters: On June 29, Microsoft said it would transfer about 100 of its mapping employees over to Uber, who were responsible for image collection and data analysis. Microsoft will now rely on partners for collecting mapping data. In general, this is a good thing: Microsoft won't be tasked with the laborious challenge of acquiring new information, just presenting it in new and useful ways. Getting out of the mapping analytics business, however, probably means that Microsoft has no plans for a self-driving car.
