Such environments exist in coastal areas and  near steel mills, also 
in the frozen wasteland north of the Ohio River, where city streets 
are covered with salt whenever there is snow.  It's rumored that car 
dealers subsidize the application of the stuff.  :-)

Warshawsky/J.C. Whitney Auto Parts of Chicago used to sell blocks of 
magnesium to be bolted to the undersides of cars to act as a 
sacrificial metal to prevent corrosion of the steel.  I don't know how 
well they worked.  Testing would be simple; suggest it next time a kid 
needs a science-fair project.
