Letter: Mosquito bikes

THERE is nothing "green" about those motorcycles that can be heard screaming like a swarm of angry mosquitoes from at least a mile away. If government is to listen to the bikers' lobby and make changes to the law to encourage the use of motorcycles (photograph, 1 April) then it must also outlaw the machines that make our lives a misery. Noise can be as damaging to health as other sources of environmental pollution.
