shop=Eco_Friendly ? What is the meaning of that shop value? What kind of services or products are sold here? Is anything from shop=* fitting? Maybe new value needs to be invented? Maybe this data is wrong and there is no shop here? Maybe it is not a shop but something else?

Why is this bus stop named "Bus Zone"?

Is Airport Trail appropriately classified as a motorway at this point, and the ramp appropriately classified as a motorway_link? There's a crossing of a bike trail here, which is something that I might expect to see on an onramp from a non-freeway, but not usually on a ramp from one freeway onto another freeway.
