the "no satellite background images" gets me to a question
that came up this weekend when i uploaded the A661 east of Frankfurt.

i found there some sketchy autobahn access/exit lines that where all
shifted according to my tracks (based on 10 tracks in each direction)

when i compared it to the sat images at zoom level 15 in the editor
this evening, it seems they where drawn based on the sat images

as a comparison i've uploaded an image which shows the distance

http://www.openstreetmap.org/wiki/index.php/Image:TrackSatDist.png

Orange is the old database content probably based on the sat image,
Brown is the recorded track of the same traffic circle
(went there on my way back home this evening, the track on the A661
matched the already uploaded carriage way),
the arrow shows the distance of 35m (according to gpsman)

just to start a discussion:
shouldn't the display of landsat background images be turned off
in scales that enlarge the sat image over it's original size
(i assume level 13 or 14)
- as an advantage that would make the display faster, while
  there are less tiles to cache
- as an disadvantage, that would also turn off the display
  of sat images in the java applet
