7x7 - Top Gear

Why do we feel guilty when we go through Customs even when we have nothing to declare? Dr Michael Argyle of the Department of Psychology, Oxford University, explains. Chris Goffey reports on how the AA trains its patrolmen to cope with around two million breakdowns a year and there are road impressions on two recently announced cars.
