I don't doubt that that will happen to some people, and if you're not confident in your ability to keep scanning for traffic, then you should take a safety pilot along. I believe I said that in so many words. On the other hand, it seems a bit arrogant to declare that everyone will have the same experience that YOU had, don't you think?
It all depends on what lengths you're willing to go to. Certainly there are CNX-80 experts, but I was unable to find any in my area. Sure I could have traveled to California or paid an instructor's travel and lodging expenses to come here, but that gets very expensive. So I joined an online users group, bought Keith Thomassen's book, and spent a lot of time reading, asking questions, and trying different things out. It took a little longer, but it worked out.
Again, what I said was that if someone has a simulator, it would be a cheaper way to experiment than flying the plane. If I have to pay an outstate instructor's expenses plus hourly or daily rate to get access to a simulator, then again, maybe it's a quicker and even better way to learn the unit (depending on one's learning style). But it's definitely not cheaper, and even if we never set foot in the airplane and did all of the familiarization using the PC sim, it would probably be a good bit more expensive that way than the way I did it.
