I've run tests with the STi-R+ and I've determined that it does NOT operate during warm-up mode. One thing I think could be modified is that the STi-R+ should operate even during warm-up mode. If you're shot with laser, you slow down for 1 minute. I get it. But laser is always an immediate thing (and protection is active rather than passive), whereas radar is simply passive...and sometimes, you only get one warning, and it happens 3 minutes from your encounter with the LEO:

If this guy was using an ALP with STi-R+ integration and got shot with laser 30 seconds before the video started, he would have been toast.
