I'd agree if it works as advertised. Level 5 or very close to it is the key. No system has shown that, much less Tesla's. In the meantime, doing a live experiment with 3,000+ pound machines moving at 30+ mph seems like a bad idea.
There seems to be a misunderstanding on what they're referring to. You with "self driving cars are a nice luxury" refers to the current iteration, while the main GP is talking about biotech and self driving cars in terms of the potential they hold, perhaps 15-30 years in the future.
We can't go straight from level 2 to level 4 without some real effort, and it's not exactly helpful when new level 2 systems can't even handle curves[0] or will continue to drive for you when you take your seatbelt off[1].
