Pedestrianizing downtown shopping streets is often hailed as a win for the environment and local businesses, but I've seen cities where it backfires. In my town, closing the main street to cars reduced foot traffic by 20% because shoppers couldn't easily reach the stores, and several long-standing shops closed within a year. Yes, it cuts emissions and creates a nicer public space, but at what cost when access becomes a barrier? Shouldn't we consider hybrid models that limit cars during peak hours rather than a full ban?
