This week's Question: Last week, Elon Musk, chief executive of Tesla, said that the electric car maker would introduce autonomous technology, an autopilot mode, by this summer; the technology will allow drivers to have their vehicles take control on major roads and highways. The CEO also announced that a software update for the Model S will be rolled out in 90 days and give Tesla owners new safety features, including automatic emergency braking and blind-spot and side-collision warnings. Some industry experts, however, are skeptical that such autonomous driving is legal and meets current regulations. Although some states have passed laws legalizing autonomous vehicles, those laws address the testing of driverless cars, not their use by consumers. What do you think?
