The user interface isn't very clear. There is no labelled link as you get for satellite/map/terrain and even hovering over the little pegman doesn't bring up a tool tip letting you know what it does when streetview is available. You only get a tooltip when streetview isn't available and the pegman is greyed out. Small changes could definitely make it better.<p>The route selection also seems a little odd. For example nothing available for Princes Street in Edinburgh but some of the most obscure backstreets are covered.<p>Having said that the odd route selection did mean I was able to locate my car so it's not all bad.
Street view is also live in the Netherlands today:
Amsterdam, Rotterdam, Edam, & Groningen are all I can find (the last two being a bit odd to begin with).<p>Still waiting on "Canal View" :)
