Lower insurance and decreased rate of accidents possible benefit of slowing down.
TOKYO, Sept. 15 (UPI) --
The Tokyo metropolitan government plans to adopt an "eco-driving" license system that rewards drivers for cutting back on exhaust emissions.
To obtain the license, drivers must meet certain criteria that prove they don't abruptly accelerate or brake, or leave their cars idling unnecessarily -- all factors that have been found to increase harmful gas emissions, the Asahi Shimbun reported Thursday.
Eco-license holders will be rewarded for their efforts, officials said, adding that a reduction in car insurance fees is one option being considered.
