Off-ramps
When adding/editing off-ramps on a motorway we want to make sure the ramp splits off from the main motorway segment at the last possible place where the driver can legally change lanes, ie. the gore point (where the solid white line starts). This is to ensure navigation instructions don't disappear prematurely causing confusion while driving.
In case of more complex off-ramps where the ramp itself branches off in different directions the location of the branching point should be mapped following the same practice.
