have you not been following the developments of self driving cars? Like the story of how google cars had problems gauging the intent of bike riders that were themselves stopped to let the car pass ... it looked like they were about to take off, so the car was too conservative and didn&#x27;t move until the bike changed what they were doing. And then, once that condition was experienced and identified, it was fixed <i>for all google cars in the entire fleet</i>.<p>I&#x27;m pretty sure the car will be able to identify and plastic bag ... not to mention a simple cargo manifest that would apply parameters about how the cargo is to be dealt with.
