I seem to remember a multiplayer racing game like this from about 1990(?) for PC/DOS.

What sticks in my brain was the fact that mines, caltrops, etc. would persist throughout the game unless somebody actually hit them. This meant that jumping out to first immediately wasn't always a good strategy as somebody behind you could drop a bunch of stuff in a pattern at a corner and a lap later the person in first would be the person to hit all the stuff.

The rocket-powered explosive skateboard was also amusing as if a couple people dropped them all at the same time you could effectively close down all but a small width of the track when they came flying around.

I wish I could remember what it was.
