Hey, David!
While your assessment is actually correct, the fact of the engine cycling may be a good explanation of why the Prius' are a little problematic. I don't know how to overcome that issue at the present, but I WILL! In fact, I'll contact my computer guru in a little while to see what can be done.
It's time I looked into this anyway! I'll get back to you here.
In the meantime, remember to "Drive it like you STOLE it!" and see what happens next...
