| What about crappy roads with worn markings, missing / damaged

| Autopilot is kind of a scam. Marketing and economic pixie dust
| from Elon over a basic camera lane assist system to make sure
| Teslas attract customers and hold their prestige and value.
|
| But no, FSD is perpetually 6 months around the corner for him.

| AI is kind of a scam --- and autopilot is just one example.
|
| _FSD is perpetually 6 months around the corner for him._
|
| And will probably remain so for decades to come.

| distribution. It is utterly frustrating.
