A full van is more space efficient than 12 bikes. I am a cyclist and I think there need to be safe routes to get everywhere in a city. Bikes aren&#x27;t enough, though.<p>The price doesn&#x27;t adjust for future optimization. It adjusts for current optimization.<p>Price-sensitive people like Grandma would go to the doctor for the same price she always does. She&#x27;d just share the ride with more people. This is exactly what a subway would do, except without the need for expensive infrastructure.
