I changed the referenced text to read: "For example, if the
probability of a catastrophe when drinking and driving once is 1/1000
= .001, then the probability of a catastrophe in 600 such events is
1-.999^600 = 0.45, or about 45%. Of course the probability of a
catastrophic event is much larger if the drinking is very heavy,
perhaps 0.1. The probability of a catastrophe in 20 such events is
1-0.9^20 = 0.878, or about 88%. Each event is independent, yet the
combined effect of repeating events has a dependent nature. This is
sometimes called the Russian roulette effect."
Which very clearly demonstrates that drinking and driving don't go together.
Though many people believe that they are not negatively influenced by
any alcohol or drugs and are still able to drive a car, truck, train,
ship or airplane.
Therefore in most countries a limit of 0.5 promille is used for alcohol
levels while driving a car.
