Wireless security has always been somewhat of an oxymoron. Upon visiting CNN today I found this article on the issue of wardriving. It's interesting to see that there is a whole site dedicated to and encouraging those to do wardriving. You can visit Worldwide War Drive for more details and tools. What is worthwhile checking is the changes in statistics from the first WWD to the most recent ones. While people are using WEP they are leaving other things at default. It makes me think there is a false sense of security with WEP enabled and the fact that people are using it.
