Saga has done some research into the age structure of the UK car travel market. This is far more than your usual PR market research. It is very well done and mighty comprehensive.
If you thought the average car traveller looks on the older side it will explain why.
Now I doubt if these facts will have any impact on the car companies or those providing services to car users (i.e garages, motorway service stations etc). These companies will continue to design everything assuming the customer is 18-35.
The evidence is there if you are prepared to look. Dick Stroud
