As a CFI, I have had the "come to Jesus" talk with several students over the years that maybe flying isn't for them. Even after that talk, I would give them dual forever if they wanted, without ever giving them an endorsement for a checkride, and I made that very clear. None of this is a great or foolproof system, and people slip through the cracks. Some of the best pilots on the planet have died making dumb mistakes. Conversely, many marginal and fringe pilots have been flying that way for 30 years. Is what it is.
