Tidy Transit

It's an ugly phenomenon, the smell of public transportation in the morning. Who knows what happened in this very bus last night, or why it smells quite the way it does.
But this morning you are taking Tidy Transit: A Self-Cleaning Bus. No questionable smells, no questionable stains, just freshly cleaned seats.
Once a day, the self-cleaning mechanism is turned on to wash away the unwanted fluids and odors of yesterday.
For that new bus smell.
