I've been out of the loop with NASCAR for the last few years and am curious about The Chase. According to NASCAR.com the points are adjusted to

1st 5,050
2nd 5,045
3rd 5,040
4th 5,035
5th 5,030
6th 5,025
7th 5,020
8th 5,015
9th 5,010
10th 5,005

I get that much. But what I'm trying to understand is do all the drivers race? Or is it only the drivers in the chase that race the final 10 races?
