Yeah, I meant specifically in reply to someone saying it should be standard. Well designed as an installed device like a breathalyzer to start the car I could see it potentially being a worthwhile tool in addition to licence revocation, since folks often still drive on revoked licenses.

But I think you’d need to design it very carefully for a variety of reasons including road saftey- taking away agency from the person operating the vehicle always has potential risks that would need to be carefully considered and mitigated as best as possible
