Running...on exhaust

Pollution levels are so high here that running after 7 AM can be very dangerous to one's health. The pollution from the exhaust fumes of vehicles is perhaps the cause of many health problems, detected or not. It is sad that the US model of automotive transportation is being copied here, and the number of vehicles on the road is increasing by double digits.

One needs runners and walkers and high speed comfortable trains, not more cars and trucks.
