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

Question

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?

You’re going to see a lot of talk shortly about tire emissions. There was a 20+ year study done on why fish are dying in Washington State I think it was. They’re dying from toxic chemicals in tire rubber dust getting washed into the river during rain.
