Is there any reason I should try to keep my car from being overgrown by lichen?

Besides, I guess, sheer aerodynamics?

I seem to remember there are some photoautotrophic lichens and others that pick up their nutrients and structure-making material from dust, but an awful lot of them have the fungal component extracting minerals from the substrate. That'd be quite not good for car bodies, yeah.

As it happens, if the lichens are growing on the aft half of the car, it might actually improve the car's aerodynamics through boundary layer control.
