While driving on a small family trip this Sunday, my father remarked that advisory bike lanes (see image above) give people a false sense of safety. Advisory bike lanes similar to normal bike lanes, but they're painted on a road that would normally be too narrow to have them. The idea is that cars in both directions use the space between the lanes, but may move into the bike lanes to pass cars going in the opposite direction.
Anything that looks like a bike lane makes a cyclist feel like it's a separate lane on the road, so they're safe. They don't think about the possibility of a car moving into their lane.
This got me thinking, are they other things, especially in the tech industry at large, that feel like they have a positive impact on security, productivity, company culture, .. but don't? I think these things can often even do damage, because we just assume their benefit is there.
