Automakers invented the crime of jaywalking (2015)
The Library of Congress has a great film taken from the front of a cable car in pre-fire San Francisco [1]. It's absolutely terrifying to see how unsafe the streets were. It wasn't just cars either: horse-drawn carts dart in and out of traffic just as cars did, pedestrians cross at-will in front of all vehicles, and at one points kids mess about jumping on the back of vehicles.It's obvious major regulation was needed, and not just for pedestrians. Pretend cars didn't exist on that street for a moment and think about the changes needed to make it safe: carts needed lanes and rules for changing lanes, cable cars needed dedicated lanes, intersections needed a system to allow traffic from multiple directions, and pedestrians were being a bit too free with their judgement calls.[1] https://www.youtube.com/watch?v=uINgSqEU26A
