How to fix that shared car smell

• The consortium will establish standards for odor measurement in AVs and create a reference database for smells that includes everything from cigarettes to fuel leaks.

Why it matters: When drivers give up their personal cars and instead become passengers in unmanned AVs, their ride experience could be determined, in part, by whether fleet operators are properly maintaining those cars.

Humans can sense an average of 1 trillion odors, according to the journal Science, so cataloguing them in a database could take some time.

• My thought bubble: I'm guessing nobody wants to smell any of those trillion odors in an autonomous vehicle.
