I don't want to be the wet towel here but, those DO seem a bit dark to me, darker then 35% - but it's really hard to tell just on photos on the internet. They would only raise my eyebrows if you were speeding or had some other probable cause. I do like a darkened tint a bit personally, but they draw perhaps unnecessary attention to yourself, not to mention other then personal preference, they serve no purpose. But, I do like them!
