Hmm... now, I'm just completely making stuff up, but since we're just dreaming here...
What would be decent would be to allow for a server client to host the game. Somethin' running on a Linux box (so it stays running for more than a day or two at a time). That way, the server admin could select whatever rules he'd like to enforce - ie HP limits and/or car type and or model blah blah blah blah.
I've got a Dual P3 board sitting here waiting for me to find a use for it...

Ok, so that wouldn't happen, but please don't rain on my parade.
