text: Most importantly, driverless cars aren't safe. In most states, driverless cars are illegal because lawmakers are concerned about their safety. This can be seen in paragraph 9 when the author states, "In most states it is illegal even to test computer-driven cars." This reveals that states don't even think it is safe to test the cars, much less use the cars on the road. Even manufacturers acknowledge that there are many issues with these cars. Paragraph 10 states, "Automakers are continuing their work on the assumption that the problems ahead will be solved." This shows that the automakers see the problems but are just assuming that they will go away. The reader can imply that the safety is being ignored because they are just assuming the problems will go away.
