Add a 4x4 vehicle profile in planner?

You should really add a 4x4 vehicle profile in the web planner. I know several people who are overland travellers in 4x4 vehicles who have your gold subscription, so you shouldn't neglect that important part of the community. That profile should have a similar autorouting logic like MTB profile, just slightly less often choosing technically more demanding trails, and avoiding trails which are less than 2 m wide (but also avoiding tarmac when there is a picturesque gravel/dirt road alternative nearby).
