Mobile phones and road safety

Sir, – In response to Robin Heather’s question about the use of mobile phones while driving (Letters, April 29th) the answer is that it is never safe to use a mobile phone when driving, whether hands-free or otherwise. Repeated studies have shown that holding a telephone conversation while driving is seriously detrimental to concentration. To justify endangering every other road user with the excuse that you have a business to run is simply not acceptable. Yours, etc,
