From Dave Robinson
Matthew Lloyd is not the first to propose “talking tarmac”
(Letters, 5 December, p 54).
At least 15 years ago, the suggestion appeared in the Daedalus
column in Â鶹´«Ã½.
Perhaps the idea was never adopted because people in power would not have
benefited. Their luxury limousines have low-noise tyres and sufficient
sound insulation to prevent the drivers hearing the warnings.
