Sir, - I note with interest the statistics resulting from the first day of national car testing (The Irish Times, January 5th). After walking up Burgh Quay earlier today, I can only hope that buses will be subject to the same rigorous vehicle testing as cars, since it was clearly evident from the fumes being disbursed that four out of the five buses present would have failed the test. If only all public transportation could be as environment-friendly as the DART. - Yours, etc.,
