I've just read about this in bland terms on the BBC your description is to be honest far more real. I can now imagine it - not sure if that is a good thing. I have a horror of being hit by a bus while driving they are just such big lumps of metal. I think we all have a certain illusion of safety in our cars and forget that they can wreak such havoc. Personally I think part of the driving test should include as assessment of whether or not a driver understands. At 17 I certainly did not! I admire you for being able to cope with the consequences of those of us who lose concentration, are unlucky or simply over confident just once and do not get away, with it.
