This sounds good and promising but it's should be noted that they do not have to answer to the FTC according to this article, it has merely been recommended in a letter to the FTC by one senator that they should investigate some specific car companies. There doesn't seem to be any new way in which they are more or less accountable to the FTC than they were or weren't already and there's no obligation on the strength of this letter to do any investigation nor any guarantee of a positive outcome if they did. A rare and nice little show of support from a member of the political class for privacy rights but nothing substantive or concrete.
