What is a potential downside of increasing alternatives like bike lanes and transit in a city?

• A. Reduced car traffic and emissions due to more bike lanes
• B. Fewer lanes for cars can lead to more traffic
• C. No impact on traffic
• D. Public transit becomes unnecessary

Answer: (B)

Introducing more bike lanes and transit changes how space on the street is allocated and how people choose to travel. A potential downside is that taking lanes away from cars reduces the road’s capacity for vehicular traffic. If driving demand remains high or the new infrastructure isn’t fully connected and convenient, this reduced capacity can lead to more congestion, longer delays, and higher travel times, at least during the transition period. In the long run, well-designed bike and transit improvements can reduce overall traffic, but the immediate downside captured here is the potential for increased congestion when car lanes are narrowed. The other options describe benefits (fewer cars and emissions), assume no impact, or suggest transit becomes unnecessary, which don’t reflect the trade-off being asked about.
