As long as someone else has the way point, invite them to a party and all of their available map locations will show up on yours. They will have the same 3 red dot icon as the "Shared" icon has.
You can just click on the places on the map and it will teleport you there. You can also gain XP by doing this. So if you have a new rider, join group with someone that is Level 8 for example and has a huge unlock % and just start teleporting to their spots to unlock the drop zones out.
The only thing it won't do, is unlock mountain missions if you aren't near them at the time you teleport in, but that just takes a bit of travelling afterwards. Not a big deal. The main problem is the drop zones.
Adding in, that discoveries of points is 300xp per point. The levels scale, but are only around 5k at level 8. I can't remember the exact amount. I will try to keep a record of it next time when I start anew after beta.
