Driverless cars good for our future
If driverless taxis roaming our cities become a reality, they would not only help cut our expenses but would also greatly reduce emissions of greenhouse gases, say researchers, including one of an Indian-origin.

New York: If driverless taxis roaming our cities become a reality, they would not only help cut our expenses but would also greatly reduce emissions of greenhouse gases, say researchers, including one of an Indian-origin. The per-mile greenhouse gas emissions of an electric vehicle deployed as a self-driving, or autonomous, taxi in 2030 would be 63 to 82 per cent lower than a projected 2030 hybrid vehicle driven as a privately owned car and 90 per cent lower than a 2014 gasoline-powered private vehicle.
The study was co-authored by Jeffery Greenblatt and Samveg Saxena from from Lawrence Berkeley National Laboratory (Berkeley Lab), a US Department of Energy National Laboratory Managed by the University of California. "When we first started looking at autonomous vehicles, we found that, of all the variables we could consider, the use of autonomous vehicles as part of a shared transit system seemed to be the biggest lever that pointed to lower energy use per mile," said Greenblatt.
One of the factors contributing to lower emissions for autonomous taxis is a cleaner electric grid. By 2030 power plants are expected to be using more renewable energy and emitting less pollution, meaning the greenhouse gas intensity of electricity would be lower.
