Driving us to .... death?

Letters to the Daily Telegraph:

Sir,
On a trip from London to Bristol, where there is about 100 miles on which the speed limit can be ignored, the difference in journey time at 80mph instead of 70mph is 11 minutes. Is the wear and tear on the nervous system, the increased chances of an accident and the 20 per cent additional fuel worth it?

Sir,
The answer to the question posed by Barbara Davy (Letters, Apr 15) - to name a piece of machinery other than the car implicated in more than 3,000 deaths every year - must be, according to the recent figures for deaths from MRSA, the hospital bed.
