because I am finding it bloody infuriating.
My child gets picked up for 'road safety issues' by a council run bus scheme. We live in a location where there is no footpaths and it's also on a very bad bend. The bus driver pull to the centre of the road to try and block the traffic going round it, but still people overtake before my child has even crossed the road. Today some idiot drove up the grass verge where we were standing waiting because he hadn't got time to stop and nearly ran us over 
If everyone just waited my child could get on the bus within less than a minute and the bus would be on it's way. As it is, everyone has to wait longer and my childs safety is put at risk because people can't be arsed to wait :(
In America there are apparently laws in place so that people do not overtake school buses when they are stationary, not sure if this rule applioes in other countries but I wish they would do something here.
