I'd say the Kerths count as a date. It would be "just work" if they were both going anyway and decided to carpool, but it seemed pretty explicit to me that they were there as a couple for the evening. I can't see Lois threatening Clark's spleen over a carpool arrangement.

"It is a remarkable dichotomy. In many ways, Clark is the most human of us all. Then...he shoots fire from the skies, and it is difficult not to think of him as a god. And how fortunate we all are that it does not occur to him." -Batman (in Superman/Batman #3 by Jeph Loeb)
