The various vehicles which pollute our country

certain two-wheelers in India which have a surprisingly high emission to weight ratio than compared to larger vehicles

How many Royal Enfield Bullets have you seen roaring across our roads, propelling their exhaust which can be felt (& heard) almost a km from their source. Or how about the carburetor induced TVS scooties which expel black filled smoke. Even the 3-wheeler tempos aren't much better. I think these vehicles need to be modified & regulated to meet emission standards. Mr Arvind Kejriwal (CM AAP)...your odd-even day scheme is an insufficient attempt at addressing th root cause!
