I agree - but I do agree with why it's there.... Here's a list of static coefficient of friction for rubber on concrete and asphalt
rubber on dry concrete .5 to 1.2
rubber on wet concrete .45 to .8
rubber on dry asphalt .35 to 1.2
rubber on wet asphalt .25 to .8
That in addition to the extra drainage grooved concrete has with respect to hydroplaning...
