some remarks:

  • probably should be enabled only with centering or centering + navigation
  • how to compute the zoomlevel ?
    • up down from the zoomlevel it was started/which was set using the appropriate buttons ?
    • fixed zoomlevels for speed ranges ?
  • NOTE: continuous zoom, which might be available with the planned clutter based mapview, would be ideal for this

An idea (is it too complicated?) Instead of using threshold to trigger zoom, it might be good idea to use it to trigger download. When download is ready, zoomlevel is changed. To get proper zoom at specific speed one might track acceleration. Greater the acceleration, lower the threshold. This might even get ICd to report whether edge/3G or whatnot is in use and take that in account when deciding to start downloading next zoomlevel. On modes: IMO walking doesn't need autozoom, biking might be limited to one or two levels that could be triggered without any acceleration sensitivity and car & train could use the same scheme. I'd advocate a buttom similar to 'center' to trigger autozooming, hence no dialogue box would be needed - just change the icon.
