We went on a walk there this weekend and I saw a confused car turn right into the bike lane instead of the road which the caused 3 cars to follow them and then there was a line of 4 cars driving in the Brattle bike lane. 3 of them panicked and exited at the first break in the blocks but the first car just kept driving down the bike lane as if they didn't notice anything wrong. I know they look a little ugly but I think the cement blocks should have the taller toblerone blocks installed on top to make them more visible in the snow and safe for the cyclists. A lost driver also might hesitate to turn into the bike lane if it's so obviously walled off
