Yeah you definitely aren't rewarded at all for driving drunk in the game. You get the cops after you, screw up your car, and it takes forever to get anywhere because of all the wrecks.
Not to mention the fact that drunk driving shows up in just about every crime drama on TV and in all kinds of movies.
The fact is that with all the media available today, kids are going to get exposed to a lot more stuff than 20 or 30 years ago when these women were growing up. It requires a different style of parenting. Even if parents don't buy their kids M rated games, some of them can still get them by pirating (yes there are 10 year olds who can use torrents) and if they don't do that there is always that one kid in class that's parents don't care and will buy him whatever game he wants. The kids are going to get exposed to it whatever the parents do. They just need to sit down with their kids and discuss the differences between games/movies/TV and real life. I don't think there would be any problems with kids learning from media if parents told them that in life there are no respawns and you don't spend just one night in jail for killing people.
