By many accounts, Tesla FSD has improved rapidly, now feels "very human," and will soon have greater adoption than any other self-driving software.[a]
Speaking from personal experience, I've tested the most recent version of Supervised FSD, v12.3.6, and it's much better than most people realize.
Once Tesla stops requiring human supervision, I expect FSD adoption rate to go "hockey-stick."
