Country Concern

In all the discussion over the removal of lead from petrol (and the atmosphere) there doesn't seem to have been any mention of the difference between driving in the city and the country.

When I realized my leaded petrol car is polluting the air wherever I drive, I feel that when you travel through the country, where you only see another car every five to ten minutes, the problem is not as severe as when traffic is concentrated on city roads.

Those who want to penalize order, leaded petrol vehicles and their owners don't seem to appreciate that, in the country, there is no public transport to fall back upon and one's own vehicles is the only way to get about.

I feel that country people. who often have to travel huge distances to the nearest town and who already spend a great deal of money on petrol, should be treated differently to the people who live in the city.
