Here's the breakdown:
* Technically: A car in park, with the engine running and lights on, is still physically parked. It's not moving and is in a designated parking area.
* Legally: Some jurisdictions might have specific regulations about leaving a car with the engine running unattended.
* Common Sense: If you're talking about the car being "parked" in the sense of being left unattended, then having the engine running would make it unsafe and not truly parked.
* Traffic Laws: Some traffic laws might define "parked" as having the engine off, but this can vary from place to place.
In summary: While a car in park with the engine running is technically parked, it's important to consider the context and local regulations. It's generally not considered safe or advisable to leave a car unattended with the engine running.
