In September 2016, Pittsburgh became the first U.S. city with an Uber fleet of driverless cars, some 100 modified Volvo SUVs. When hailed by riders, the vehicles will come with a human back-up driver. Pennsylvania transportation rules do not explicitly ban driverless cars as long as there is someone behind the wheel, and Pittsburgh has established no particular requirements for the experiment. This has been dubbed "greenlight governing," as the mayor gives companies free reign to help turn Pittsburgh into a technology hub.

In answering the question, you may:

• Investigate the safety record for driverless cars to assess if safety concerns are unfounded.
• Consider whether this will reduce jobs.
• Notably, this program in Pittsburgh saw its share of problems

What ethical issues arise here?
