Wait, can I not carry in a Waymo?

Found their rules page: "Do not carry weapons of any kind in the car"

That seems... naive? Plenty of people carry pepper spray or a knife with them. Not even ever intending to use them as a weapon.

When I go to the range, I travel with a locked case that contains my pistol, which inside has a cable lock. I couldn't take that through a waymo?

What about some kid buying a goofy mall katana they are going to put on their wall?

Like, obviously brandishing a weapon should be disallowed, but merely having anything that's a weapon? Seems fraught.
