"Tim Douglass"
Some years ago there was an experimental device on some cars to
prevent you from driving while intoxicated. You had to punch in a
series of randomly generated numbers accurately in a certain amount of
time for the car to start. I don't recall the details, but it seems
the company got sued into oblivion when some woman tried to get away
from a rapist and couldn't because she was too scared to punch the
right numbers. I would love for there to be a foolproof way to prevent
people from driving when they have been drinking, but I doubt any such
thing is possible and would probably still hesitate to have it
required.

At least a couple of years ago, a similar type was around. My nephew had to
blow in to a tube in order to start his car. The JUDGE require that.
