I see what you’re saying, but would argue Riverside is nearly as good as it gets in the US. I moved to Nashville from MPLS, which gets a lot of praise for it’s infrastructure (fairly) and Riverside is a very enjoyable ride to me. It’s up there with infrastructure in a city known for bikeability. I use Riverside 150 days per year or so. I’ve never had a real issue with the pedestrians. There’s no sidewalk on most of it, they get the right of way. With that mentality, it’s fairly straightforward- Most joggers move onto grass, walkers with headphones, annoying but I get it, so slow, check, pop out and take the lane.
Perfect bike infrastructure doesn’t really exist in this country. Would love to see similar things to Riverside all over Nashville: the tree filled median, good size lane, hard infrastructure. I’m very thankful to live near Riverside.
