Yes, as far as I know they have a resolution of only 4 meters.

Leading to the funny situation that a roundabout which is mapped
precisely with 100 nodes looks ugly on Garmin compared to a circle
that is mapped with only 8 nodes.

I already experimented with the --reduce-point-density-polygon=NUM
option but without much success.
