Strange Engine Issue

Tonight, as I was sitting on a hill waiting on a light, clutch depressed, foot on the brake my engine started to rev to about 1500 rpms and continued to climb. I put the car in Neutral, took my foot off the clutch and the engine raised to about 2500 rpms. (No, my right foot was not touching the accelerator.) So I revved the engine and the rpms dropped but then started to climb back up to about 1500. Does this have anything to do with hill assist?

Never seen that. Hill assist shouldn't affect the throttle at all.

I had this happen with my A8. Pulled into my street let up off the gas and the car was still going 25mph without touching the pedal. I smell a recall in our future!

It was not dark enough for headlights yet, but the radio was on. I'm not sure I understand the question though.

If there were a heavy electrical load, the computer might raise the idle to enable the alternator to provide increased output. But I can't imagine it going up to 1500 rpm unless you were running an arc welder off the car.
