content: Don't you need to show ID to buy kitchen knives in Britain?  I know you need ID for spoons over there. On a serious note, if you ever get pulled over by cops, roll down all your windows, take the keys out and put them on the dash, license/insurance on the dashboard and both hands on the steering wheel.  This helps relax the environment and will give you a better chance and decreased fine/warning.  I hate cops but we currently have to live with them.
