Some ramps can be simply at the end of an otherwise dead end. Announcing take the ramp (in this case even to the right) does not feel like a reasonable announcement here, especially since the two turns are so close to each other.

To me, personally, it is unclear what would be a good announcement for these combination of turns, but I feel that we probably cannot do much better, except for ignoring the direction_modifier to turning onto the ramp.

EDIT:

continue on ramp? or just omit it, since there is no choice of route involved

Yeah I would say the expected behavior here would be that we don't emit an instruction since there is no action needed on part of the driver.
