Aside from assorted roadkill, the things I see most often along the road while running are banana peels.
The banana is a great snack for drivers: a piece of fruit encased in a disposable wrapper with a built in handle. It’s not a great idea to let a banana peel fester in your car, even for a few hours, so many of them go out the car window.
I think motorists who throw garbage out their car window are dirtbags, but something biodegradable? That’s not so bad — but folks, can we please try and pitch them off the pavement?
There are two reasons for this: the first and most obvious is the hazard they present to pedestrians, because everyone knows that people slip on banana peels. The other is that I suspect things like apple cores and banana peels may be attractive to critters. Could this be related to the roadkill? Very possibly.
