Why? I would expect manual drives to diminish in popularity over time. It's harder to use, and does not give any benefits at all, other than a slightly cheaper price, and a slightly higher performance if the user is knowledgeable.
An auto transmission is so much better in every respect, and the performance improvements in manual hardly comes into play during every day use.
I consider the ability to use manual transmission vehicles, of which there are many, a benefit. Last year I visited my aunt for a week and traveled around the state with her in her car. I couldn't share in the driving, because she has a manual transmission.
