Nah, any reduction is good, including social encouragement for others to join you in things like going car-free. Plus, outside of the environmental effects, cars are horrifically unsafe things when used en masse, and every one we take off the road makes our neighbors safer.

They did have an effect on birds though. I think it was almost entirely mitigated by painting one blade black, if memory serves, but it was based on some truth.
