Judging by all the down-votes, I'm guessing people think I'm anti-bike. I'm not. I think putting traffic curb extensions so a bike lane is forced to veer into traffic is dangerous for both the cyclist and shitty for traffic. It's probably indicative of poor planning. See the area around Muskrat Studio as an example: https://www.google.com/maps/@42.3945437,-71.1107064,3a,75y,223.07h,68.33t/data=!3m6!1e1!3m4!1sJcZX86qjZyfil0BGZhoJ3g!2e0!7i16384!8i8192

You can actually protect a bike lane BEHIND a curb extension, but it's just weird shit like this all over https://bikeportland.org/2015/10/30/postcard-from-austin-curb-extensions-that-dont-block-bikes-167143
