Leaving aside the likely-correct sibling comment that they don’t own the land, double and triple parking is difficult for robots to do quickly / safely. It probably isn’t a high priority and they might be more bottlenecked by getting vehicles in or out of the lot.
I’m also confused why they’re parked like that. Land in SF is expensive. Wouldn’t you just double and triple park them?
There’s a couple of non-waymo cars in the lot so they’re probably only renting some of the spaces in the lot.
