Bacteria, viruses and allergens are ever-present. Disease-causing germs enter the vehicle through the air conditioning and can spread more easily on the inside, especially in small, confined spaces such as a cab. A contagion from passenger to passenger is thus more likely.
Especially since the corona virus (Covid-19) became a global pandemic, hygiene standards have become increasingly more important. Furthermore, instances like smoking inside the car or the transportation of pets can emit unpleasant smells, making the air feel heavy and thick.
