My automatic wipers work fine, but I have to turn them on each time I drive (well, each time when it might rain, but this season in Florida that's every afternoon).

That's only slightly less than "automatic" isn't it?

Is there a way to say "just stay on"?

Incidentally contrary to several threads here, I find mine adjust quite nicely from intermittent to fast as it rains harder, and quit very quickly when it stops.
