http://maps.yahoo.com/ has done it again and added another awesome feature. To recap:

maps and directions (duh)
saves history and address book (login to my.yahoo.com)
click on restaurants, banks, shopping, churches, etc and see dots on any map for what exists in the area. very cool.

And now, real time traffic! On any map you can click the "traffic" button and it colors all the freeways and tells you how fast cars are moving. It tops out at 55mph but it's still super cool and useful.

update: Aki showed me this cool option to show you all the wireless spots on any map. They are displayed using the stupid Centrino logo. Centrino: Being two years behind Apple is better than never figuring it out at all.
