Check your street view(blue line) near your business place.. Google now shows pins for places/businesses to map users who are in a blue line mode(Google Street View for roads/streets). It is possible that Google is going to go further and start letting people jumping inside places that have 360 degree tours directly from GSV (blue line) mode.

It brings another good point for a business to have a 360 degree business tour done and submitted to Google Maps as Business Street View.  Google Map viewers soon may be able to visit your business online directly from Google Maps while they are in Street View mode.
