Believer on the Train?

I overheard a conversation on the train this morning, as an elderly gentleman pointed out to a lady beside him a news article about a Japanese car that can park itself. No hands required. OK, this is actually pretty old news, but he was discussing it nonetheless.

And then he said, "Before long I believe we'll be able to pull over into an express lane and the car will drive itself."

I thought that was a pretty interesting little conversation to overhear.

Was there a believer on the southbound train this morning?
