Look they just get in the way and make the path super narrow. I mean it's not interesting, it's just annoying having to dodge them all the time. Maybe it's just me but I'd rather have a smooth ride without worrying about hitting some random concrete box. They seem like a weird choice for a bike path honestly.

Yeah I always figured that stuff was just for the hangar, but now I notice those little fixes everywhere!

Honestly that whole debate reminds me of when I tried to learn guitar. I watched a million free youtube tutorials and got decent at chords, but hitting a wall. Then I paid for a few real lessons and the teacher instantly spotted my bad hand position, something no app ever could. Sometimes you need that outside human to see what you're missing, even if the free stuff gets you pretty far.
