There are numerous companies working on artificial noses that car manufacturers have been looking to integrate in order to have an equivalent of white noise generators but of course for smell. There is no reason why just sampling the air for particular elements would not also be possible and improvement is always going to happen. I can imagine not only having cars watch eye movement to eventually tell you to quit looking at your cell phone to having cars detect smoking and sensing children in the car and notifying you to stop. So alcohol present in a car should be a flag the car can at least suggest to you that it is concerned

These are completely different things. To detect intoxication for drunk driving, you need to accurately estimate the concentration of alcohol in the driver's blood. Detecting the "smell" of alcohol in the car does not do that. It's also likely impossible to detect blood alcohol concentration in real-life conditions by sampling ambient air (what if they're the DD driving home a bunch of drunks? what if the window's open? what if they had liquor spilled on them?).
