问题:

Is there any way to highlight/display on Google/Bing/(any other map provider) Maps whole street (from the beginning of the street to the end of)?

I know the existence of Polyline in Google Maps API, but it's just connecting two latitude points, and there is no way of making it automatic so I could display any street in some city.

Also I was thinking about Directions, but many street are 2 way, there is no guarante that you will mark whole street and it's just now user friendly. Example

You may want to check Mike Williams' article on how to snap points and polylines to streets with the Google Maps API:

Snap points (and polylines) to street

Especially this example:

Click on the map and a path will be drawn that follows the streets.

Take a look at OpenStreetMap. (Google and Bing won't let you access their underlying street data.)

You can show a map with OSM tiles, and use the API to query for the features you're interested in displaying on the map. OpenLayers is a javascript mapping library that could support this.

Here's a view of Chicago showing street vectors and other features overlaid on top of the map tiles:
