Self-driving cars can help to significantly reduce greenhouses gas emissions that causes global warming, a new study reveals.
Researchers from Lawrence Berkeley National Laboratory studied the amount of carbon gas emission from different forms of automobile. They found that driverless cabs could provide transportation while caring our environment.
They reported that in the year 2030, self-driving cars could produce 94% fewer carbon emissions per mile than today’s conventional gasoline car, and it could be cheaper than taxis with drivers.
Jeffery Greenblatt, one of the authors of the study, said that the use of self-driving cars as part of a shared transit system seemed to be the biggest asset that contributes to lower energy use per mile.
The benefit of using this smart car is utilizing the maximum size of taxis for the number of guests, a practice called as “rightsizing.”
“Most trips in the U.S. are taken singly, meaning one- or two-seat cars would satisfy most trips. That gives us a factor of two savings, since smaller vehicles means reduced energy use and greenhouse gas emissions,” he state in a press release.
The researchers also looked at the cost-effectiveness of driverless cars. They estimated that users could save up to $150,000 per vehicle, because of its energy efficiency.
Self-driving cars offer other benefits like optimal routing tips, smoother acceleration, and the ability to reduce wind resistance by moving closely behind other smart cars — which allow vehicles to save energy.
