Here definitions of all points. Just as info or to re-read.
The use of shaping points is to change the shape of the route like driving a certain road. But these are more or less optional.
When you decide on your trip to drive elsewhere the SP can be skipped. More or less when the point is behind you. I use thid often to skip some optional loop. If I am tired, I just drive straight and after some hints to turn, the SP should be skipped amd all is fine.
This is very practically, as the point is automatically skipped and Kurviger does not force you to manually skip or even to pause an re-plan.
Means, I drive normally with re-calculation. The re-calculation will calculate to next point. Dependent how far you are away from your route, it may happen that the recalculated route deviates from your planning, as from your current position a better route is calculated to the next point. For me acceptable, or I just set more SP to stabilze my planned route.
If you do not accept deviations, switch recaluation to off, and in case you deviate, perhaps there is a a road under construction, drive by orientation until you are back on the route.
A lot of words. Just create some routes with SP’s and drive another way. Learning by doing and check what happens.
