SAFER and similar styled racing barriers are certainly one of the biggest saftey improvements in auto racing. Good track design can also make it MUCH safer, obviously Nascar ovals can't have the huge paved run-offs of the newer road course, and F1 circuits, but they have come a long way.
The one with Gordon @ vegas this year (http://www.youtube.com/watch?v=ErWPGQBzlV0
) highlights probably the biggest issue with Nascar tracks at this point.
