The demand for fuel would be allot lower if people stopped driving their kids 1 mile to school every day.
Sorry but I just can't stand the "I blame the school run" mentality.
Have you ever tried getting young children up, fed, washed, dressed, out of the house & into school in time for 0900 hrs every morning? If you haven't, then let me assure you that it requires organisation on an epic scale & that's when using a car to get there! The prospect of having to go through an even greater rigmarole & leave home even earlier in order to walk there, is even less favorable!
A mile is a very long way to walk when you have rather small legs due to only being five years old, especially in the middle of winter & when its raining or snowing! Then there are the younger siblings to consider, because as a parent you have to take them with you on the school run (strangely you are not allowed to leave them at home unsupervised, whilst you take your older kids to school!). They certainly can't walk a mile there (& back again afterwards) twice a day, so they will have to go in a buggy, which you will have to get out each day unfold, (put the rain cover on if its raining) and fold away again after use. Now because they wont be moving around to keep warm whilst sat in the buggy, you will have to wrap them in many extra layers in order to prevent hypothermia! (during changeable weather in late autumn & early spring they may well then over heat too & then you have the worry of a febrile convulsion to contend with as well!) Then you have to take your life in your hands (& theirs), crossing roads in the half light with small children in tow, whilst idiots on their way to work are paying zero attention to the road, whilst doing their make up in the mirror or arranging the days meetings on their mobile phones whilst driving (being a pedestrian in rush hour is dangerous enough, let alone when you have a small children & a buggy with you).
In short I have had to do the school run on foot on a number of occasions, it's highly impractical & it really isn't much fun! I would far rather cycle to work, or take the bus to the supermarket, than not take the car on the school run! I therefore make no apology for using the car to take my kids to & from school!
Unlike commuting, the school run is actually a far more efficient use of fuel than the most, simply because it involves more than one person being transported in a car! How many people could far more easily stop driving the short distances to & from work each day & walk or cycle instead? Now I can only apologise if you are actually the parent of young school age children, but it seems to me that it is generally only those that don't actually do the school run, that seem to find the need to criticise it!
