Letter: Uninformed consent

Sir: In California, which renews driving licences every four years, one is given the option upon renewal to designate oneself as an organ donor (letters, 1 March). This is indicated on the licence by a small pink dot sticker. In the event of an accident it is easy for an official to see that donor permission has already been given, and that the organs may be removed. Both my husband and I have pink dots on our licences.
