As soon as there is any air over the car, it will start spinning. It might even generate a bit of power.

I believe most vehicles have diodes to stop them from creating electricity and throwing things off - remember there are signals and communication happening. It could potentially cause issues.

Maybe the indicator doesn't use a diode? Or it's wired up wrong allowing the fan to back feed the car's electrical system?
