We have them in Green Valley (retirement community) No one knows how to use them. There are a lot of type 'C' folks here. I learned how to use them from traveling to Boston. Basically it goes like this. GTF out of my way, I'm coming in. If you signal, I will block you. As long as there is any imaginary room, there is room to merge. Chances they like their car more than you.
I wish more people here were like the Massholes I miss... not really, but driving in Boston was better than the 'E' rides at Disneyland.
