Our current modes of transport do not protect drivers or passengers from breathing environmental hazards in the air around them, and without actively preventing in-cabin contamination, air pollutants can rapidly accumulate within vehicles. 


We Spend a Lot of Time on the Road


An average person spends around 3-4 years of their life on the road, either driving or as a passenger.  Further, most people are exposed to higher levels of pollution on the road than anywhere else. In addition to the serious long-term health effects of unmanaged and prolonged air pollution exposure, air pollution can also cause serious health impacts in the short term. For example, a 14-day average PM2.5 exposure of 7.07 μg/m3 or higher has been linked to an estimated 4-5% increase in asthma symptom occurrence.


Air pollution exposure is also known to impact cognition and decision-making, with especially serious consequences for those required to be alert and aware while driving: one study examining air quality’s impact on decision making in 596 chess games found a 10 μg/m3 increase in indoor PM2.5 concentration increased player error probability by 26.3%.


Air Quality In-Cabin Can Often be Worse than the Outdoors


Experts say that in some scenarios, like when we’re stuck directly behind a truck or another polluting vehicle during rush hour traffic, in-cabin pollution can be 9-12 times higher than outdoor pollution levels. Research into average pollution exposure over a 96-hour period found that professional drivers in London were exposed to four times the amount of black carbon pollution while driving than at home - 4.1 µg/m³. 


This amount was also a third higher than the measurements recorded at one of London’s busiest roads (3.1 µg/m³). The study also found that as drivers moved across London, black carbon pollution inside the vehicle often exceeded 100 µg/m³ - much higher than the World Health Organization’s recommended exposure safety limits for 24-hour periods (15 μg/m3 for PM2.5 and 45 μg/m3 for PM10).


The Links Between Seasonal Allergy, Sneezing & Driving

Air pollution isn’t the only environmental breathing hazard impacting drivers and passengers on the road. Seasonal allergy symptoms while driving can also be dangerous: For example, sneezing has been directly linked to millions of road traffic accidents and is a common risk factor for drivers with extreme sensitivities.


Research revealed 1 in 4 UK drivers suffer from seasonal allergies and 25% of this group believe their ability to drive is negatively impacted by allergic symptoms. 

The FDA also warns that some antihistamines - found in many over-the-counter seasonal allergy medications -  can cause drowsiness, and recommend particular caution to be taken when driving a vehicle due to potential temporary impairment of reaction times, coordination, concentration, and vision.


360° Environmental Intelligence for Automotive Operations

Research conducted before COVID-19 already highlighted the importance of safety to drivers above other factors. Post pandemic, ‘safety’ has taken on a new layer of meaning as focus shifts more to unpredictable and invisible health threats around us:

  • 91% of consumers feel indoor air quality is highly important for managing COVID-19.

  • The air quality control system market is experiencing huge growth, projected to reach over $144 billion by 2026.

  • BreezoMeter found Google News search results for ‘air pollution' increased by roughly 6719% from 2016 to 2020, reaching almost 8 million articles. (N.B  Numbers may vary per user based on Google’s search results settings and geographical location).

Increasingly common extreme weather events such as wildfires are also drawing new attention to environmental hazards and the threat they pose to public health and safety: 

  1. In 2021, WHO updated their air quality guidelines to reflect new evidence to highlight air pollution is more dangerous than originally thought. Pollutants commonly associated with vehicle emissions saw major maximum recommended level reductions. Annual PM2.5 was halved from 10 μg/m3 to 5 μg/m3, while annual NO2 level was cut from 40 μg/m3 to 10 μg/m3.

  2. Wildfires are getting worse, burning larger and more frequently. In 2021, by October California alone suffered over 7000 wildfires, burning nearly 2 million acres, rendering many roads inaccessible, and causing major evacuations and traffic congestion.

Air pollution sensors inside the cabin are a great approach to enhancing vehicle air quality monitoring. However, a sensor-only approach for in-cabin air quality safety management also comes with a range of limitations.

To overcome these limitations, automotive OEMs are now looking to complement existing sensors, or replace them altogether, with comprehensive alternatives like cloud-based environmental intelligence:
