It has some value as a single driver car, it has much more value if there are two drivers in it.
I've found the learning curve to be pretty steep for most of those systems. I find simple video where you can see most of the track and driver inputs to be fairly-useful, but mostly after the fact. With the short time between runs at most regional events, you rarely have time to do the overlay of driver runs to compare, and since most of the 'lipstick' cameras, downloading the recorded videos to some device where you can review the run usually takes more time than the actual run itself. I guess the stuff could be useful 'semi-live' if you had a quick way to grab the memory card out of the camera and get it plugged into a laptop of tablet, but with everything else that usually happens between rounds, you really need a 'crew member' dedicated to just the datalogging stuff to get the time to get the data transferred and reviewed.
Still, we DO record, though, both data (we currently use the Petrel SoloStorm on a Galaxy Tab 4), and video (we have two Re-Play cameras, a 1080-Mini (our first RePlay camera) we use to record output from our A/F meter, and a PrimeX we use to record driver actions and the car run with the camera pointing out the windshield), but rarely view the output until we get home and have decompressed from the event. The last even video should be fun to watch, since I did ground-loop the car on my last run.
All-in-all, I probably have about $1000 in the current package, but have gone through a CamFX (worked fine until the controller quit booting) and a Canon digital video camera (didn't at all like the vibrations it was exposed to, and would frequently just quit working and shut itself off, even when recording to a memory card).
It seems the next step up in data logging is about 2X+ what we've currently spent. Still mulling that over, but hopefully we'd get something a bit more user-friendly.
