Don’t drink and phone


I hereby put this idea in the public domain hoping that it will be implemented (and not patented) as soon as possible.
As probably many of you know (yes, you too) drinking more often than not, alters your state of mind and inhibitions. This results in some bad judgement calls, by example, calling people at 3AM or sending messages you really shouldn’t (or should you?).
I propose that an additional sensor be added on phones that measures the alcohol in the users breath. The phone could then warn the user not to make that call or it could present the user with a password or math test question in order to discourage it’s use.
What do you think?
