I think having the cross symbol on the stop light instead of a solid color is confusing.
Paris is a biking city. They have velo stations every couple of blocks. You can rent a bike for 30 minutes and it only costs one euro. We loved it. Despite the scarcity of space Paris has bike lanes everywhere. Some of them even go against traffic! This is a stop sign that is only for the bike lane that goes against automotive traffic. You have to have a lot of faith in the system to proceed on green. (Actually, that’s not true. Parisian drivers are extremely aggressive, but are also extremely aware of their surroundings, and the net result is a scary but safe environment.)
