When you are out driving, sometimes there are places which smell so bad you wish you’d diverted around them.
That isn’t always possible. though (I’m thinking of a particular landfill site next to a motorway I regularly use).
Today’s invention is a software program which runs in vehicles to help deal with roadside stench.
When anyone drives past such a smell, they can record its location via an app.
A bad-smell map is thus developed.
This is then used by your car, so that a few minutes before you enter a foul zone, the windows close and cabin ventilation automatically switches to recirculation (and might even inject some extra scent into the airflow). This could also take into account known wind direction, so that the switch-on would be optimally timed.
