Honda Insights have a "gas cap sensor" that lights the "check engine" light when the gas cap isn't tight enough. "to prevent VOC emissions in California" I'm told. But after nearly 20 years, the sensor isn't reliable anymore, and is hard to find and expensive, so the practical thing is to dike it out.
I've no idea how the "drunk driver" detection is supposed to work; but how is it going to be any more reliable or less troublesome than the gas cap sensor?
Does anyone even in the offices of anyone voting for this crap have the slightest idea what technology they're mandating or how reliable it is? Is there any understanding or concern for people with "auto brewery syndrome" or any of the other edge cases that will trip some folks up?
Or is this purely kabuki "see us care" and damn the cost?
