This was directed at the OP who said taxi&#x27;s are OK because you can call the taxi company, but self driving cars aren&#x27;t because if you don&#x27;t call before someone else rides in the car you&#x27;re stuff will be gone.<p>My response is that a restaurant works the same way. If you don&#x27;t return or call before someone else sits there, you&#x27;re stuff will be gone.<p>Addressing your point, taxis and buses immediately drive off after you step out of them. Do you avoid them because of this?
