Is it just me who'd love something like this to happen to me? Would be great fun tracking down the source of the problem (if it was my car; probably less so if I was in the house...)

There's a lot of options to try to isolate the problem, just thinking out loud here -

a) Back into the driveway returning from work. See if alarm goes off. Next morning, see if alarm goes off as you drive out.

b) Remove fuse for reverse assistant. (Stupid sensor thinking IR, ultrasound or RF sure-fire sign of break-in)

c) Remove fuse for reverse light. (Stupid motion detector confusing light for potential intruder)

d) Rev it up a little before shifting into reverse. (In case a resonance is the cause)

e) Roll out of the driveway in neutral. (Would be surprised if this triggered anything - if the car's movement was the cause, alarm wouldn't go off immediately upon shifting into reverse, only when it moved)

f) (...)

f) Try putting car in reverse with the engine off

Earlier quoted context omitted.

His WRX doesn't have backup sensors.

It could have backup sensors. Rear cross detection and blind-spot detection is an option package. This allows my car (2016 WRX Limited) to warn me about cars flying by when I am backing up out of a parking spot for example.

I have that on my Mazda 3 and it's absolutely brilliant. The range and sensitivity of that system is rather amazing.

I love reading about interesting problems and creative ways to solve them. I used to wish for the same. But then I was given a super annoying one.

In my apartment I heard this beep about once every 90 seconds or so. I tried ignoring it for a while hoping it'd go away. And just so at the right frequency and infrequent enough Impossible to determine direction. But also just loud enough to be annoying after hours and hours. I spent several hours trying to pinpoint it. Including putting my head up agaisnt numerous neighbors doors to see if it was coming thru the walls.

I ended up downloading a dozen different audio apps for phone. And found only one that gave out an accurate enough histogram of dB volume level. Most weren't good enough. I needed to differentiate between 2 and most were sensitive enough of reading. I was able to triangulate the direction thru several patient iterations.

Turns out it was coming thru the wall.

Be careful what you wish for. Because you might end up with something arbitrarily dumb and annoying!
