Navigation instruction: Make a U-turn 120m away and come back ??

When I start to navigate from home to the starting point of a predefined course further away (which I downloaded from the Internet), then the Explore instructs me to make a U-turn 120 meters away at an intersection and then again pass my own house in the correct direction towards the starting point of my course.

The road in front of my house is an asphalt road where two trucks can easily pass each other.

Is this a device for biking or for oversized trucks?

Funny? I experienced the same in France, mountainbiking in the middle of nowhere with a lot of serious climbs, and at that time the U-turn (on asphalt) was 1 kilometer away, which wasn't funny at that time!

Does someone else have the same experience, eventually with other Garmin devices?
