Generally I agree with the principle that things you own should not be enforcing laws. I'm far more annoyed at the encroachment of the "nanny state" than I was in my younger days... So i'm sympathetic to the viewpoint... But this feels more like "design machine with appropriate safeguards so owner cant kill self/others" ... like SawStop or Bosch REAXX on circular saws or a Riving Knife on a table saw. Designing a tool/device/vehicle to avoid injury, especially when that injury can impact people around them is a good thing. Trains have devices to (attempt) to ensure the driver is paying attention to prevent accidents. With numbers like "over 10000 deaths due to drunk driving each year" and "over 100000 injuries related to drunk driving accidents each year" it starts to look like allowing people to operate these vehicles while under the influence is something the manufacturers should be preventing to avoid injury to the public.
