Sir, – I have just come home from crossing the M50 from Exit 16 to Dublin Airport and back. At long last I have discovered why there are three lanes on this wonderful route. The inside lane is for those of us who drive at or about the speed limit, the middle lane is for those who travel at up to about 20 per cent over the limit and the outside lane is for those who think the rest of us are wimpy idiots. – Yours, etc,
JACK KELLY,
