How to create Road Trips

I've been creating road trips and viewing them but I can't seem to figure out how you get the map of the whole trip.  There is a tiny thumbnail map when you create a trip that shows up in the list, but how do you get this map as a larger map, similar to the lifetime map feature?

Hello James,

Looks like that on my side, I do not have the option to save as roadtrip, is there anything I am missing ?
My mistake, one should use ROAD TRIP SEARCH and not drive search…

Thanks,

Fly
