I disagree. I have a Tesla Model S and it drives perfectly fine for me every day in stop and go traffic. At higher speeds it works well too but it is prudent to keep a close eye on it. I think autonomous driving in limited situations is still helpful even if it doesn't work everywhere.
I think within a year or two, Tesla will be able to drive long distances on major freeways with little or no human intervention. That's a huge value to me as a driver.
If my car can handle both stop-and-go traffic and long-distance boring driving, I can handle the rest no problem.
