When Autorun, and Windows 95, were being developed, CD-Rs were multi-thousand dollar machines with media that cost $15+/disc, and USB was still being hashed out in the research labs. As such, the only real removable media that would have been used under Autorun would have been professionally mastered CDs, which had a $450+ minimum outlay for a master, and usually a minimum lot size atop of that, which was more than most people up to no good would have been willing to spend. Yes, as Autorun became a more viable attack vector, more protections should have been put in place, but in 1995, it was pretty low-risk.
