No. That doesn't make sense. Turquoise lights are the new standard to identify self driving cars. That means in the near future there will be more models with self driving capabilities than the average person will be able to keep track of. If I put turquoise lights on my newer Subaru, it isn't unreasonable to think that other drivers will think that I have a self driving car. I can't imagine there will ever be a Subaru Impreza used to help fight fires.
How about "If you put blue lights everyone will think it's an unmarked police car" then? The argument works the other way around too, if you put turquoise lights on a 1999 Subaru nobody will think it's self driving.
