Nah, guys. The bike boxes make sense in southern England as the traffic density is huge (larger than anywhere I've been except expect Asia/India.)
Have the bikes at front and filtering through the stopped traffic is the safest and they're aren't any hidden cyclists.
Maybe in a rural area they don't make sense, but everywhere I've seen them they're heavily used. Even at a midnight on a weekday there'll be multiple bikes in them.
I like segregated stuff better (like CPH) but that's not available is ultra dense 1000-year old cities always.
