I stopped riding FTD a few years ago:
1. I was banned from the org after my ex-girlfriend started dating one of the founders of FTD (Bill). She was quickly brought onboard as a staff member because of the relationship, and they decided that apparently my presence would be a "problem". I was eventually invited back once my ex and bill were fired from FTD and started Calitrackdays (which failed not long after it started). Obviously, I didn't care to return.
2. At a Sonoma event, when the track went cold for the lunch break, one of the founders friends showed up in a ferrari and they went out to hoon on a cold track - one of the staffers later told me that they almost got banned from the track for it.
3. At the same Sonoma event, we lost a full session because the bill hadn't yet been paid by FTD. All the riders just sat in the auxillary parking lot waiting for Sonoma Staff to let us in. Losing track time at an already expensive track was frustrating.
4. At yet another Sonoma event, I watched the founder (Augie) show off down the front straight only to end up rear-ending a novice rider in the beginner group.
5. At a THill East event, I asked an instructor to follow me and critique my line/body position. The advice he gave was later laughed at and called "utter bullshit" when I brought it up to another instructor after implementing the advice led to slower laptimes.
Beyond that, I have also experienced the general lack of professionalism in how the org is run - riders regularly ignoring flags, dive bombing riders in corners, unqualified instructors, instructors ignoring poor on-track behavior, etc.
Overall, the extra few bucks to ride with a better org has proven time and time again to be worth it.
