I had lots of CD and mp3-CD players with good anti-skip. Some would even buffer enough or the song to stop the CD for several seconds at a time, especially so on my later mp3/ATRAC CD players. The crappier ones added crappy audio compression to fit it's tiny memory, but better ones could do the raw data and had no (at least to me) loss in quality and later the mp3/ATRAC ones would just buffer the actual file data.

I don't think I've ever experienced a car CD player skipping due to shock. I'm sure it could happen, but I don't do much trail driving at high speeds personally.

I listened to my CD players while biking, hiking, and more. No reason to leave the CDs at home unless you already upgraded to one of those fancy hard drive mp3 players.

Yeah it was probably around 2003 I listened to all my music on MP3 CDs I made and it had like 30 seconds solid of buffering that I never managed to hit unless I sat their purposefully shaking my player in my hands to watch the buffer meter go down.
