TBC is still pursuing government permits and contracts to build tunnels. Not having succeeded in every case is not the same as abandoning the project.

The new roadster is delayed, not abandoned. It's known to be in active development and is very likely to be demoed this year. Wrong timeline but not abandoned.

The Tesla semi is on the road daily and the factory to build large quantities is almost complete. They're hosting a "factory inauguration" event next month. Certainly not abandoned.

Tesla has already committed to replacing hardware as necessary on cars that purchased FSD in the past so that they can run unsupervised as promised, after Tesla has unsupervised FSD working. Certainly the timeline was wrong but again, clearly not abandoned.
