  == Original Research ==  With respect to SkyTran and ADA, please read WP:OR. You need to find a reliable source that says SkyTran is not ADA compliant. What you are attempting to do is original research, quoting the ADA standard and interpreting it for SkyTran. That is inappropriate for an encyclopedia.  The closest we have to a reliable source for SkyTran ADA compliance is this, which claims: Designated stops have electric lift capability to special vehicles for ADA compliance. So your information about ADA compliance may be out of date.  In any case, you have a history of debating issues and posting your opinions on the PRT talk pages, and you've started up again recently (see the archived San Francisco debate, which had nothing to do with the article whatsoever). You have been informed multiple times that this is inappropriate, and I'm once again informing you of that fact - see WP:SPAM and WP:SOAP. I'm asking you again to cease this inappropriate use of the talk pages. I will immediately archive such content unless there is direct relevance to the article in question.
