Although the act is known for having led to the funding of a wave of electric-vehicle charging stations, it also called for a final rule to be issued in 2024, requiring all vehicles sold in the US to have the ability to passively detect when drivers are under the influence of alcohol and to prevent them from driving.

All good and well, except that such technology does not yet exist as a commercialised market-friendly original-equipment vehicle component.

While others have been frantically trying to make inroads into such technology, Asahi Kasei has a Swedish subsidiary which has been working on alcohol and gas detection sensors for other applications for 25 years.

The Japanese company is now working with a range of role players, from automobile manufacturers to Tier 1 suppliers, to make the tech commercially feasible.

The company’s North American director of mobility told a US auto industry publication that the legislation took everyone, including his own company, by surprise. He said everyone expected it to happen in Europe first but owing to activist groups in the US such as Mothers Against Drunk Driving, the tech will now more than likely be implemented in the US first.

It is exactly this faulty assumption regarding Europe, that led to Asahi Kasei acquiring the Swedish tech company, Senseair, five years ago.

Senseair is hoping to develop a sensor that can be seamlessly integrated into vehicles without the need for new cabin hardware. Drivers would exhale toward a small sensor that could be embedded in the steering column or side door trim and await a quick pass/fail reading on the alcohol content of their breath.

It will use an algorithm that detects the amount of ethanol on a driver's breath compared with naturally occurring carbon dioxide.
