I'm still mad we quit switching to metric.
I was working with a guy in Canada and he was sort of complaining about it being confusing because they switched when he was a kid in the 70s, and I told him we were doing it too until jackasses stopped it. Apparently he never heard that.
I drive on the only metric highway in the U.S. every day.
@billyjoebowers California has a number of highways which are at least dual-marked for distance (but not speed). It's a tiny thing, but I certainly appreciate it.
