Would it be possible to add a new source of speed limit data?
TomTom's speed limit data would be really nice.
I've been correcting OSM speed limit data for a while now but I doubt it will ever get much better than this.
And since the charge estimator relies heavily on the speed limit data, it can really mess up the predictions if the speed limit data is not correct on long trips.
