The highway authorities of Western Finland had had some problems with people vandalizing the public roadside restrooms they had installed for the urgent needs of travelers And, one might surmise, to reduce the number of patches of yellow snow along the side of the roads. The solution was not closing down the restrooms altogether, or investing in video surveillance. No, instead the Finns decided to put in text message controlled locks. The cost of opening a restroom is nothing more than the regular text message, but the senders number is kept in a database for some time, allowing maintenance to track down vandals. The state of Swedish roadside restrooms is usually somewhere between horrible and core melt down, so this idea might be something for Swedish Vägverket to study?brbr
