(I'm mainly posting this here because I know that, in the past at least, the maps team have engaged with people on this forum (Mark Brown springs to mind IIRC) and I don't have a whole lot of faith in Bing Maps' bug reporting link to get much attention, although I will report it there also)
I was trying to search for some (UK) postcodes on Bing Maps this evening and it autocorrects the perfectly valid postcodes I enter (example N5 1RN). Why it thinks NW5 1RN would be a better place to go to I have no idea but it's somewhat annoying (and fortunate that I spotted it). If you click the "we autocorrected it, click here to go to what you typed" link the original search term works fine and returns the correct address.
I hope someone at Bing Maps reads this and turns this off for postcodes...
