Now that I look through my rides, I'm seeing Matched Rides grab some stuff with a little one-block-over-one-block-up variation, but I'm not surprised to see how few matches are coming up - I tend to ride in a general direction one year and a different general direction another. Within those, there's a lot of overlap, but often some variation as I allow for construction, boredom, exploration, etc. Still, a cool feature.
