MRS M Pelham (MSA Madness: letters last week) has no need of motorway serviceareas as she clearly does not use the M40.

MSAs were opened at Cherwell Valley junction 10 and Oxford junction 8 in 1994 and 1998.

Like Mrs Pelham, I am fortunate in joining the motorway locally but unlike Mrs Pelham I appreciate that motorists from central London may well have been on the road for at least an hour, and a stop would be welcome. In addition motorists joining the M40 from the M25 could have been travelling for 50 miles without stopping.

There is a similar need for motorists travelling towards London. The bad image of MSAs lies mainly with the shortsightedness of the Department for Transport.

If more sites for MSAs were designated at the planning stage of a motorway, and developed and opened at the same time as the motorway, then each area could be significantly smaller than at present and not so intrusive on the environment.
