In order to look their best at Defcon and Usenix Security, members of the UW CSE Security and Privacy Research Lab equipped themselves with t-shirts displaying the text of the waiver they were required to sign before testing their hacked automobile on the runway at Blaine Airport.
We can confirm that no damage was done by the car at Blaine Airport. We are not so sure about the impact of these t-shirts at Defcon and Usenix Security.
