Getting an accurate enough sample from your breath without cooperation and breathing into a tube is probably impossible. Even then there still is the question of whether that sample is actually human breath from the driver.
Apart from that it's probably not a good idea to let someone drive who doesn't have any recent-ish experience driving, especially in dangerous situations.
- kawsper 11y agoIn Denmark the have talked about an alcohol-lock, so you can only start the car if you breathe into a tube. But that is probably easy to cheat if you want to. Oh, it seems like it already exists: http://alcolockusa.com/compliance/index.php?route=common/home http://alcolockusa.com/compliance/index.php?route=common/hom...

- voidz 11y agoThe Dutch already had this, but there were too much issues, legal and technical, to sustain it. If the Danes are thinking about implementing, hopefully they can do it in a better way than the Dutch.
- willvarfar 11y agoHere in Sweden, I don't know of any legislation but alochol locks are not unheard of. They are fitted to a lot of company work vehicles, and are increasingly popular in the cars of normal people who could never imagine themeselves drink driving because insurers will give discount. It was in my local paper that the local district nurses were having trouble with them because they had to wash their hands in alcohol after each visit, and this was enough to make the car lock up sometimes, leaving them stranded waiting 30 minutes until they could try again and start the car and proceed to their next house call.
- akerro 11y agoThat's a good idea to punish people who never drink.

- pbhjpbhj 11y agoEye movement and speech changes are probably sufficient to indicate a warning for drink/drug driving (DUI), but even then the car should still run IMO. Smoothness of ride is probably a very good indicator of impairment too.
- Shivetya 11y agoThere 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?).
