Trucks aren't all that common in the UK outside of professional necessity, or for people who have to haul large loads on a regular basis. A family would sooner drive a station wagon/estate car (if they regularly chauffeur kids and sports equipment, say, or go on longish family vacations by car). Also, it's quite common for people to do their daily shopping on foot (SHOCK!HORROR!), especially when living in/near the center of their village/town/city.

A train is often a cheaper/more conventient means of transportation between two cities than a flight.
