From Michael Kellock
Roland Matthews interprets his results, which showed that drivers using hands-free car phones fared worst in an oral word game, as evidence that they were most at risk of an accident (4 May, p 27). Surely it is equally logical to argue that they performed badly because they were paying more attention to their driving than those using other types of phone.
From my own experience with hands-free phones, I often asked callers to hold fire while I negotiated demanding sections of road. I believe that this was at least partly because the conversation was taking up only a minor part of my attention.
