Nice, *if* it is optional
There are several nice features there, but I hope they are optional and can be disabled.
For example: showing only the streets pertaining to the route is nice - until the street is closed due to some event Google doesn't know about, and you need to see what options exist.
Also, the article isn't clear: is this about the maps on the web site, or the Maps application in Android? If the latter, once again, I wish they would fix it to allow multi-point routing: something they have been promising for YEARS.
