My daughter Lisa is researching courses for ASL to take this fall. She took a few classes in high school and loved it.
At a daycare where I worked they used some sign language with kids who were being taught it at home. (just the basics tho) The two year old who sat and did the sign for "more" at lunch also had to say "may I have more please?" when I was on lunch duty. He was fully capable of speaking. One day he said to another kid who also did sign language, 'you have to use your words!' when he signed for 'more'..
lol
With the other staff he used only sign language..good grief..
I don't drive but am very good at USL...
