Everybody in society is increasingly lazy and would prefer to drive or take the bus rather than walk, especially when it is freezing cold and the pavements have not been gritted. So we have a choice, take the car or take the bus. I welcome the increasing use of buses by school children and the related reduction in use of cars (mainly SUVs) on the road. The fact that buses are full is a sign of greater use of public transport and consider that the alternative is probably not walking but more cars on the road.
