I would like to see a navigation/map feature where you can discover approximately where you will be at given time... e.g. on a journey you need to stop to take a meeting or other activity, where you will need to stop at a specific time. I often drive about 300 miles in the late afternoon but stop to participate in meetings at a certain time. I usually have to search for a safe place to park first several minute before. Even with markers on the map with estimated time stamps would be helpful. 15, 30 or 60 minute time stamps on the map would help. What I do now is take a guess, and add a stop to the route and see what the ETA is. it usually take a couple of stabs to get it.
