Y2 was a little worse because the media was reporting everything from cars stopping to power plants blowing up. I had someone on a forum argue with me for the longest time trying to convince me that because the date was displayed on the dash of his Mercedes that the engine would quit on y2k. I went so far as to dig up spec sheets on a Motorola 68332 (popular microcontroller used in engine computers) and code examples to show how it wouldn't.
I never heard from him after y2k,may his mercedes blew up
