Looks fine to me. I think the unsafe thing is speed. Top speed of a cable car is 9.5mph. No vehicle appears to be going over 15mph. There's a cyclist pretty casually keeping pace with the cars. https://youtu.be/uINgSqEU26A?t=153

"Results show that the average risk of severe injury for a pedestrian struck by a vehicle reaches 10% at an impact speed of 16 mph, 25% at 23 mph, 50% at 31 mph, 75% at 39 mph, and 90% at 46 mph. The average risk of death for a pedestrian reaches 10% at an impact speed of 23 mph, 25% at 32 mph, 50% at 42 mph, 75% at 50 mph, and 90% at 58 mph."

Slower speeds mean a collision is less likely to occur. We're pretty good at moving in crowded conditions without frequent collisions at low speeds. See also NYC sidewalks.

Also, it appears the video is slowed down. I played at 1.5 speed to make my estimates
