I've chosen to show this YouTube video because of the manner in which the school pupils on board the very wet vehicle behaved - very well indeed. You can tell this wasn't filmed in an inner city and not just from the greenery. Skip to the 1:10 mark to see the Dennis Dart/Plaxton Pointer go through some very deep water indeed. Normally the 'bow wave effect' sees little water enter the bus, but the pure distance of flooded road ensured lots of kids had wet feet.
Hopefully no action has been taken against the driver. Admittedly his cursory remark about not leaving anything on the floor was woefully inadequate but the other option would be to find somewhere to reverse and try a different route, which isn't easy on these roads and with the ground at saturation point already, using the entrance to a field to expertly reverse could have resulted in the vehicle getting stuck.
If nothing else the kids enjoyed it - and were ready for it, as the video description said they had a similar journey on the way to school.
