Intractable Potsherd
" Not wearing a seatbelt does not affect other road users, it only makes the results of any crash worse for the individual concerned."
Not only does it affect other road users, eg. road closed while the medics carefully extract you on a spinal board as opposed to you opening the door and getting out, it affects every taxpayer by making it more expensive to put you back together again.
Still, as long as you have the right to be a twunt, eh?
