Avoiding traffic and using an electric vehicle instead of a ICE one. In Bay Area traffic an electric drone can do a delivery in five minutes that would take a car thirty. And the Zipline style high hover + tethered descent drone is quieter than a car. I’m not sure if these are using that style or the low hover type like Amazon had been using, which are much louder.

    Quieter than a car? I thought these make loud buzzing sounds

    It heavily depends on how close you are and their hover system and how much work has been spent to make them quiet. You probably heard about the Amazon ones, which are loud and hover low to the ground. There are other ones, such as the ones Zipline makes, which are quieter to begin with and hover very high, using a powered descend module on a cable. Those are basically silent from ground level.
