Yes, there's no reason to force the extra slow speeds that most plazas seem to want. NY is the worst offender on this, I think, at 5 MPH. The system, even as used in Massachusetts, works at highway speeds (don't ask me how I know). I've used the high speed lanes in NJ, and they do work essentially the same way. There may be a bit of lane overlap in the reader field, but it's still a query-response to a vehicle passing under it.
