Here's video of a trip down San Francisco's Market Street from 1905.

It's remarkable how lawless the streets were. Vehicles and people and horses are all weaving around each other with no direction. According to Wikipedia, the painted street lane only became prevalent in the 15 years after this video because cars and buses became more popular—and crashes more frequent. And thus began the death of the pedestrian-friendly road. (Also note: No fat people in 1905.)
