But now you’re misusing “acceptable”.

We would need to get to the other side of acceptable for widespread use of autos (self driving vehicles). It’s not an unachievable goal you always try to get closer to. That word is your originally used “ideal”.

It’s not just pedantic. I’m not the only one who thought you said something you apparently now didn’t mean, because you used words you apparently don’t understand. The words you use are vital to your being understood.

You could just humbly admit your origonal mistake in language, and nobody would give you a hard time.
