greg, you're right it is stupid. but jim is also right, it is just what you do when you're there and 'in the heat of battle' (even though it is not a battle).

it is very hard to stop the adrenaline taking over and keep it totally sensible, but the more times you have been, the easier it becomes. you realise that it's ok to try and do a fast la when it's quiet, but if there's other traffic then you should all give each other plenty of room
