That strange feeling you're describing is a common illusion called **"vection"** — specifically **induced vection**. Here's what's happening:
* When you're parked and the car next to you **starts to move**, your brain receives **visual cues** (like motion in your peripheral vision) that suggest **your car is moving**.
* Since you're not feeling actual motion through your body (no vibration, no engine noise, no acceleration), there's a **conflict between your visual and vestibular systems** (the inner ear system that helps with balance).
* The brain sometimes resolves this conflict by **temporarily convincing you that you're moving** — often that you're rolling backward — even though you're not.
That’s why it feels real for a moment: your eyes are saying “we’re moving,” even though your body isn’t.
You can snap out of it quickly by looking at a stationary object, like a signpost or curb. That reorients your senses.
