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-electric-suv-lidar-sensors-drunk-driving 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.
