Google Maps has been reminding me of the exit of the interchange. How come there isn't one? ?

The simplest way is to go out according to the number of the exit suggested by Google, you just need to count the intersections.

"Don't get excited, maybe there's a problem with my app."

At first, I always had to look at the map to determine whether to go straight around the island or to turn left or right. Later, I found the intersections too complex, so I simply counted the exits and never worried about it again. When entering the roundabout, I only looked behind me and didn't have to worry about the left side. The left side should always give way.
