Real view is dragging the little guy from the lower right conner to a spot on the route and it shows a current picture of that spot. It puts you at a close up ground level view.
As noted above, it's called "Street View." Note that Street View is not available for every road. (I doubt "flying view", which I suspect is part of Google Earth, is either.) When you are in Goggle Maps, simply click on the little orange person icon without dragging it. Roads for which Street View is available will become highlighted. Then you can drag the orange icon to a spot. I have found that sometimes it bounces back to his spot. If that happens, highlight the roads again by clicking on the icon and then click on the portion of the highlighted road you want to view.
You know that Street View is also available on Ride With GPS. For example, here is one day I have planned for a tour in June:
https://ridewithgps.com/routes/18149964You can see the same orange person icon in the lower, right corner. Note that clicking on him in RWGPS doesn't work like in Google Maps. You have to drag the icon into the field and drop him down at a point on a highlighted road. In the example above, you can see that a short portion of the route (between ~mile 13 and mile 19) is not highlighted when you drag the icon into the field. That's because the road is an unpaved pass that was, for whatever reason, skipped by the Google vehicle that takes the footage for Street View.
