The law specifically calls for passive sensors as part of "Advanced drunk and impaired driving prevention technology". A breathalyzer that you blow into is an active sensor, and as it's been around for decades is not that advanced.
You can Google Scholar the DADSS citations yourself about how the technology works.
The regulations haven't been created yet. This bill says the experts need to figure out those details, and if it isn't possible, to let Congress know.
Well, I'm very skeptical about whether it's possible to do this passively. Analyzing driving behaviour seems unreliable, and more importantly, it's too late. Analyzing ambient air in the vehicle includes passengers in the test and won't work with open-topped vehicles. You need something that singles out the driver before the car starts driving.
Maybe, if the car requires a button press to start, that button press can also be used to analyze the blood somehow?
I'm skeptical too, but section 24218 (e) makes it clear that it may take 10 or more years to be put into place. (If it has been delayed by 10 years then Congress needs a special report.)
Most cars aren't convertibles. If a convertible has its roof down, then maybe there will be a special clause.
Furthermore, breath and blood were only the first two methods I tracked down, from DADSS. The text I quoted earlier mentions technology from Volvo, which https://www.theverge.com/2022/9/21/23363673/volvo-ex90-elect... says is in the EX90. ("Volvo’s EX90 electric SUV will have laser sensors and cameras that can detect drunk driving.")
The law is clearly written to allow that alternative, which would work for convertibles.
There appears to be a lot of research on the topic, and I have (checks watch) a total of 75 minutes knowledge of it.
