2/🧵
🚦 A major source of congestion in cities is poorly-timed traffic lights.
(Yes, I know, we should just have fewer cars.)
🚗💨 They're also a *huge* source of lung-killing pollution. It's 29x worse at intersections, because of those stops and starts.
You might say "oh, how foolish, surely there is a 'smart' traffic light option?"
💰 And there is. But it's expensive. Good luck paying for it at all 300,000+ of America's traffic signals, much less the billions worldwide.
