Arrival icons imply a turn

The left and right arrival icons imply a left and right turn, respectively, with a curved arrow:


The Mapbox Directions API and OSRM use the arrival maneuver modifier to indicate the side of the road on which the user can find the destination (or whether it is straight ahead). The modifier does not indicate a turn direction.

This is problematic especially for driving directions, because very often the user will not perform a conventional turn at all. For example, the user may need to parallel park, or they may only intend to drop off a passenger.

I'm not sure what a suitable replacement glyph would look like. It may be cheesy, but how about a hand pointing to the dot from the left or right? I think it would even be reasonable to reuse the straight arrival icon for both left and right arrival.

Start with src/png/dark/direction_arrive_left.png and compare it with the arrival icons discussed in the issue. Determine a replacement glyph that communicates the destination-side arrival without implying a turn; done means the left and right arrival icons no longer suggest conventional turning.
