Someone has put together an 800 MB 'special edition' of Carmageddon, and it's expansion pack 'the Splat Pack', and the package also includes some fan-made vehicles, fan-made levels, fan-made pedestrians, and some new or upgraded textures. It runs natively on Windows (meaning that it doesn't require the high PC specs that a DOSBox game does), and works great on my old Windows 10 laptop. You can set the game's resolution, aspect ratio, etc, by editing the 'ddraw.ini' text file in the game's folder. I know that this is in the DOS forum, but the original post references DOSBox, so he/she isn't trying to run the game under pure DOS.
It's a really great all-in-one package, just download the .zip file, unzip it to a folder, edit the ddraw.ini file, and play*. Unfortunately, the download (from a well known game/mod site) includes the official game data, meaning that I can't post a link here. But no one can stop you from searching via google.
* Actually, also read the user comments on the download page. It includes some details of what to change in the text files.
