I have used it for the two years that it's been available and I love it. Track Pass has several uses, not just scanning a driver. The first year, only ten drivers could be scanned and they included the most popular and a couple of others. Last year, they included the entire field and you can change drivers at any time. You can also scan the field, but that's a mess. Other uses for Track Pass include following qualifying. They give you three different ways to watch, one being watching a cicle with the car number in it going around the track with the pole leader at the same time. They will always compare to the pole leader. During race day, you can, as I do, watch the cars (circles with the car numbers and colors) go around the track in the appropriate position. You can use just the top ten, or pick and choose which cars you want to watch. There is never a commercial so Track Pass watchers know when there is a yellow probably about 80% of the time before TV only watchers. Also included is the gap between the cars and the leader in seconds until they are a lap down. You can follow your driver and see if he is gaining or losing ground. I like it because I always know where my guy is at all times and if he's losing ground or what. The track image with all the cars is indeed small, but unless the cars are all together, you can see the gaps between the cars. The track image is worthless at Daytona and Taledega because they are all so close. But again, the run down is current and if a car makes a pass, it's real time. You don't have to wait for the scrolling score at the top of the TV screen.
They usually include a free pass for Track Pass sometime during the year to try and sell it. You need Java to run the program and it does not include another program they sell which puts you in the car of the drivers. Keep an eye out to see if they will include Track Pass for a free trial and give it a shot. As I mentioned, I used it the last two years. The first year because it was free to me (Road Runner customer) and last year, it was not free, but something like $18 for the year. If they go up this year, I'll not purchase it, but as long as it's under $20, I'll continue to use it.
