Uber announced recently that they are doing deliveries with self-driving trucks [1]. Are those discontinued? I know they stopped the self-driving car work, but haven't seen anything about their self-driving trucks. Not sure how much of the technology is shared since Otto was ostensibly focused on self-driving trucks.
