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.
