Obesity and other unintended consequences of driverless cars

Fewer people will die in car accidents. More work will get done. The environment will be less polluted. The driverless revolutions will be mostly amazing. They are not, however, without their drawbacks:

The mere act of sitting in a car for an hour or so each day drastically increases peoples’ risks of developing life-altering conditions like obesity and heart disease. They worry that once the stress of traffic and overt dangers of car travel are gone, people will spend more time in their rolling barcaloungers.

This is a real and valid concern. We could hope that with the reduced cost of transportation, folks would be planning more trips to the hiking trail, park, or gym.
