It will naturally have to be hardwired into your car so deeply to prevent tampering that only a certified mechanic at your dealership can maintain it.
Skip-Shift
Beginning in the late 1980s, GM added a solenoid actuator to the Chevy Corvette's six-speed manual transmission. If you eased away from a traffic light and shifted between 12 and 17 mph, then the computer-controlled solenoid would lock out the gate to second gear, guiding the lever into fourth. This "skip shift" saved fuel because of lower engine rpm and pumping losses. It was a tiny gas savings, but enough for the Corvette to avoid a gas-guzzler tax. If you were in any kind of a hurry (and if you weren't, why would you drive a 'Vette?), then the solenoid did nothing.
Still, the feature was universally hated, but owners could disable it by disconnecting just one wire. The owner's manual even had a photograph of the solenoid, showing where the wiring to the computer was connected. The photograph was cleverly captioned to caution drivers not to disconnect this wire, or the skip-shift function would no longer function.

But what about my right to be an inconsiderate piece of shit and jeopardize the lives of everyone around me because I can't not have 8 drinks on a Wednesday afternoon?!...because some jackhole driving around completely sauced in a 1978 Honda Civic is totally going to be stopped by adding a couple thousand dollars to the price of a car, and then a couple thousand more when the "drunkard detector" suddenly breaks and the car has to be towed for repairs.

Also, the jackholes that I know who seem to think that drunk driving is amusing are exactly the same sort of assholes who have the know-how to hotwire a car's computer to ignore a feature like this
You're right, things have been going swimmingly, we should just continue to do literally nothing about drunk drivers.
You really think that won't be investigated if a car that shouldn't start if the operator is impaired, starts with an impaired operator and ends up getting pulled over or wrecking? That's the first thing that will be looked at lol, and one an assume there would be hefty fines/jail time for attempting to remove, alter or bypass the device.
I would completely be for this if I thought the technology was there. But the fact that I could accidentally blow high because I used mouth wash or any other number of potential short-comings just makes it seem not viable at this moment.
So a surface Google search reveals that 30 minutes after using mouthwash you would blow a 0.00
Its not a serious issue some of you are making it out to be
