That seems like an increadibly complicated way of doing this, in Sweden, all public transport busses I have been on in the last decade have had interlocks with breathalyzers, people convicted of drunk driving will often have an interlock like that fitted to their personal car as well.

Just seems like a way easier way to do this

Here are the actual reciepts from Congress.gov

SEC. 24220. <> ADVANCED IMPAIRED DRIVING TECHNOLOGY.

(a) Findings.--Congress finds that--
        (1) alcohol-impaired driving fatalities represent 
    approximately \1/3\ of all highway fatalities in the United 
    States each year;
        (2) in 2019, there were 10,142 alcohol-impaired driving 
    fatalities in the United States involving drivers with a blood 
    alcohol concentration level of .08 or higher, and 68 percent of 
    the crashes that resulted in those fatalities involved a driver 
    with a blood alcohol concentration level of .15 or higher;
        (3) the estimated economic cost for alcohol-impaired driving 
    in 2010 was $44,000,000,000;
        (4) according to the Insurance Institute for Highway Safety, 
    advanced drunk and impaired driving prevention technology can 
    prevent more than 9,400 alcohol-impaired driving fatalities 
    annually; and
        (5) to ensure the prevention of alcohol-impaired driving 
    fatalities, advanced drunk and impaired driving prevention 
    technology must be standard equipment in all new passenger motor 
    vehicles.

(b) Definitions.–In this section: (1) Advanced drunk and impaired driving prevention technology.–The term ``advanced drunk and impaired driving prevention technology’’ means a system that– (A) can– (i) passively monitor the performance of a driver of a motor vehicle to accurately identify whether that driver may be impaired; and (ii) prevent or limit motor vehicle operation if an impairment is detected; (B) can–

[[Page 135 STAT. 832]]

                      (i) passively and accurately detect whether 
                  the blood alcohol concentration of a driver of a 
                  motor vehicle is equal to or greater than the 
                  blood alcohol concentration described in section 
                  163(a) of title 23, United States Code; and
                      (ii) prevent or limit motor vehicle operation 
                  if a blood alcohol concentration above the legal 
                  limit is detected; or
                (C) is a combination of systems described in 
            subparagraphs (A) and (B).

        (2) New.--The term ``new'', with respect to a passenger 
    motor vehicle, means that the passenger motor vehicle--
                (A) is a new vehicle (as defined in section 37.3 of 
            title 49, Code of Federal Regulations (or a successor 
            regulation)); and
                (B) has not been purchased for purposes other than 
            resale.
        (3) Passenger motor vehicle.--The term ``passenger motor 
    vehicle'' has the meaning given the term in section 32101 of 
    title 49, United States Code.
        (4) Secretary.--The term ``Secretary'' means the Secretary 
    of Transportation, acting through the Administrator of the 
    National Highway Traffic Safety Administration.

(c) Advanced Drunk and Impaired Driving Prevention Technology Safety 

Standard.-- <> Subject to subsection (e) and not later than 3 years after the date of enactment of this Act, the Secretary shall issue a final rule prescribing a Federal motor vehicle safety standard under section 30111 of title 49, United States Code, that requires passenger motor vehicles manufactured after the effective date of that standard to be equipped with advanced drunk and impaired driving prevention technology.

(d) <>  Requirement.--To allow 

sufficient time for manufacturer compliance, the compliance date of the rule issued under subsection © shall be not earlier than 2 years and not more than 3 years after the date on which that rule is issued.

(e) <>  Timing.--If the Secretary determines 

that the Federal motor vehicle safety standard required under subsection © cannot meet the requirements and considerations described in subsections (a) and (b) of section 30111 of title 49, United States Code, by the applicable date, the Secretary– (1) <> may extend the time period to such date as the Secretary determines to be necessary, but not later than the date that is 3 years after the date described in subsection ©; (2) <> shall, not later than the date described in subsection © and not less frequently than annually thereafter until the date on which the rule under that subsection is issued, submit to the Committee on Commerce, Science, and Transportation of the Senate and the Committee on Energy and Commerce of the House of Representatives a report describing, as of the date of submission of the report– (A) the reasons for not prescribing a Federal motor vehicle safety standard under section 30111 of title 49, United States Code, that requires advanced drunk and impaired driving prevention technology in all new passenger motor vehicles; (B) the deployment of advanced drunk and impaired driving prevention technology in vehicles;

[[Page 135 STAT. 833]]

                (C) any information relating to the ability of 
            vehicle manufacturers to include advanced drunk and 
            impaired driving prevention technology in new passenger 
            motor vehicles; and
                (D) <>  an anticipated timeline for 
            prescribing the Federal motor vehicle safety standard 
            described in subsection (c); and
        (3) <>  if the Federal motor 
    vehicle safety standard required by subsection (c) has not been 
    finalized by the date that is 10 years after the date of 
    enactment of this Act, shall submit to the Committee on 
    Commerce, Science, and Transportation of the Senate and the 
    Committee on Energy and Commerce of the House of Representative 
    a report describing--
                (A) the reasons why the Federal motor vehicle safety 
            standard has not been finalized;
                (B) the barriers to finalizing the Federal motor 
            vehicle safety standard; and
                (C) <>  recommendations to

That’s dumb, what if I swerve to dodge a car that jumps out in front of me? Will their car also detect they didn’t have the right of way?

Think of all the needless, endangering police pursuits this kind of technology could stop. Not my carbureted '85 Shadow 😁
