There's an alumni perks website, and you can book cars through there, but the discount wasn't nearly as good as the corporate code. I still have all my old business cards from when I worked there, but I'm not sure if it's enough, and I am concerned, like others have pointed out, about what would happen in some sort of emergency or accident scenario. The younger me would have said screw it, take the risk, but now it doesn't seem worth the potential trouble.
