Passage Summary: The author thinks bike lanes are a bad idea for safety because more accidents happen on roads that have them than on roads that don't.

Conclusion: Adding bicycle lanes to existing roads is unlikely to make cycling any safer.

Reasoning: Data shows that roads with designated bike lanes actually have a higher number of collisions between bikes and cars than roads without them.

Analysis: This argument suffers from a classic correlation-versus-causation error. The author assumes that the lanes themselves are the cause of the accidents, or at least fail to prevent them, without considering the volume of traffic. It is quite possible that bike lanes are installed on the most dangerous, high-traffic roads specifically to mitigate existing risks, or that these lanes attract a much higher number of cyclists. Look for an answer that points out the failure to account for the relative number of cyclists on these different types of roads.
