I don’t know why, but my thought was the same as the third most voted comment in the thread too. The collision avoidance system, which I would have guessed was ultrasound, but the guy on reddit says it’s microwave. Either way, that could be picked up by some kind of sensors in a house alarm system.

We live in a crazy world.

I don't know, I would tend to side with the theory that the car engine sound at the specific RPM and power output matches the resonance frequency of one of the house windows. Resonance can creep up in many phenomena.

His WRX doesn't have backup sensors.

The reverse lights triggering motion detection and engine/transmission vibration both seem plausible too.

Not in my opinion because this would have been a problem before with other cars and alarms. Or motorbikes.

Without knowing the details of the alarm system it is hard to have an educated guess.

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.
