Here is an interesting example which illustrates everyday events:

Blackberry roulette :

Driving a motor vehicle while talking or texting on a cell phone.
"Each time I see someone driving and talking on the phone I say to myself something's got to be done about these dangerous people; but nothing ever is. They just keep motoring along playing Blackberry roulette until one day their carelessness alters the life of an innocent."
