If car tires are always losing rubber as they drive, how come the roads are not coated with rubber?

585 viewsOther

I have to replace my tires every 60 000-100 000 KM as the tires wear down and the rubber comes off as I drive. If this is happening with all cars, why arnt the roads coated in rubber? Is somebody cleaning the tire rubber off the road? Is it getting washed away from the rain and into drains/the ocean? How long does it take for rubber to degrade that has come off the tire?

Roads are covered in rubber. Literally every spot where tires touch, there is a layer of rubber.

In some places this is very apparent; on turns, lights/stop signs, high speed ramps, etc, etc.
