When you send Bob Smith et al around the country it obviously makes sense to have them in cars, but when they need to whizz around London wouldn't it make more sense to have someone on a motorbike?
One episode in this year's series had one of them (I think it may have been Ewart, what a star!) grinding through London traffic to get to Westminster Register Office, with all the attendant problems of parking etc. I thought at the time that someone from your office could have got there in about 30 minutes door to door by tube (Farringdon-Baker St 10 mins, plus about the same walking time either end, at the most).
Perhaps Bob and Ewart don't see themselves in cycle leathers, but maybe there's someone in the office who does? It would make great TV, too!
