I've started using Google's My Maps feature for planning both an upcoming trip to California and some semi-regular motorcycling routes.
I've figured out how to create maps and share them with people, but I'm having difficulties with the directions functionality. Once I've saved a route I can't seem to do anything with it; I can view the route on a map but that's it. This is okay I guess for walking but it's obviously pretty useless for driving or transit.
How do I start the route? As in: get directions, traffic, time estimates, navigation etc? At the moment I'm looking at the saved route on the map and just copying the source and destination locations into a new directions page on Maps, but this obviously doesn't give you the actual same route that you customised on My Maps.
