I just read this, and I believe it is good news!
I'm guessing ELIO has used this same information while getting the State laws changed to accommodate the autocycle?

Elio Motors not only uses this information to encourage changes in state laws but they were also actively involved in getting the AAMVA to write these recommendations in the first place. The official AAMVA video on this issue even includes the Elio P3 in it.
