The ability to set a pre defined course. Where you select course selection it will have options like “User choice 1”, “User choice 2” and so on. Where you don’t have to worry about turning at the turn points and add the u turn option as well for example see below.
Effectively this means a GUI course plan editor, but is a great idea.
Many of us (for example) want to ride the front of the mountian but then not do the back, this means chosing an option not quite right and then using manual controls all the time once we wish to divert from the chosen route. If you miss a turn it’s a pain in the back side… :-)
