This reminds me of a situation I saw with another autonomous car company's vehicle in SF a couple weeks back. I truly didn't know what the correct move by the vehicle should have been. The situation: The vehicle was on Vallejo crossing west to east over Sansome Street, a one-way, two-lane thoroughfare. For Sansome, there is no stop sign here, but there is for Vallejo. The vehicle stopped at its sign, then began to proceed across the intersection, until two pedestrians entered the crosswalk from south to north along the far side of Sansome. The vehicle stopped in the middle of the street to wait for the pedestrians to cross. There was no cross traffic coming, but what if there were? Seems like a situation ripe for a side collision, especially because Sansome is brisk at this point. I really don't know what the capabilities of the sensors are, or how situations are assessed, so I'm assuming it did what it did based on its situational awareness. Wondered if the vehicle could have backed up to the stop sign it came from if there was cross traffic, or if it could have broken the rules and gone around the pedestrians if there was danger of a side collision.
