China’s Shenzhen is the world’s first “quieter” megacity thanks to electric cars

China’s Shenzhen is the world’s first “quieter” megacity thanks to the city’s increased reliance on electric vehicles, according to Bloomberg (runtime: 1:26). The majority of Shenzhen’s vehicles — from personal vehicles to buses and taxis to dump trucks — are electric, which reduces both the noise and air pollution that are emblematic of large metropolises. Behind the charge away from combustion engines and towards electric vehicles is Chinese auto manufacturer BYD, which envisions a fully electric China by 2030.
