A9 towards Nürnberg after Greding before Hilpotstein the Autobahn is straight, downhill and has no speed limit, that should do the trick.259km/h indicated are reachable in my 4s, but never 260 yet.
Is the GPS recorded speed also 258 km/h?Whoever cares: It should be set at 250 kilometers an hour. Surprisingly, he doesn't take it too seriously and drives pretty much exactly 260 km/h. Checked it with a GPS tracker app too. A friend sent me this photo.
