If you know people are going to rate badly, then why even upload it?  The whole point of uploading, for me, is getting people to download and like the ride I built, not download it and say it sucks.  I'd put more time into it and fix it.  It can be fixed somehow, just find out how.  Send the track around to a few people and see if they can fix it.  But I wouldn't upload it until its fixed.  Unless of course its something minor.
