#5 Tweak the segment lengths
While NASCAR took a huge step forward when they finally announced segment racing would be implemented into the sports top three series, the change still needs some tweaking. In fact, NASCAR really needs to look at shortening the length of each stage, which will create less of an opportunity for a leader to get a way from the field and allows for multiple restarts.
Beyond that, it would allow for NASCAR to tweak the final segment of the race and make it a 20 lap shootout for the win. Not only only will that give every driver one more restart to try to go after the win, it also creates an interesting situation for fans and makes the end of the race just that much more lucrative to watch.
