Hold up, I just realized something.

The daycare center is often located on a long, straight stretch of road, or with BW/BW2 it had an interesting little song that changed whether you were moving or not

In fact, sometimes it's the longest single stretch of straight road in the entire game.

And it's often shortly before or after you get your bike. (Again, BW2 is the exception)

Somebody, or even multiple people at GF think that spending hours riding your bike back and forth on the same route is good game design.
