Yeah, you don't need a conspiracy to end up where we are. You just need cars to be very-beneficial to owners when most things aren't built up with car infrastructure and most people don't own cars (and they are! That's true!); and for us to start catering to that in our infrastructure-planning since, you know, it's better; and for there to be a hard-to-see-in-the-moment tipping point where suddenly everyone needs a car because everything's built with cars in mind and everything's very far apart now, but also everyone's worse-off, in precisely the ways that cars were suppose to improve things (time savings, especially), plus some others, than if we'd never had widespread private car ownership in the first place (which, there was such a tipping point, and we blew past it many decades ago). Self-interest takes care of the rest.
The default assumption should be that people who benefit from auto sales are actively trying to block public transportation. It's foolish to think otherwise.
The accuracy of significant elements of Snell's 1974 testimony was challenged in an article published in Transportation Quarterly in 1997 by Cliff Slater.[48]
Recent journalistic revisitings question the idea that GM had a significant impact on the decline of streetcars, suggesting rather that they were setting themselves up to take advantage of the decline as it occurred. Guy Span suggested that Snell and others fell into simplistic conspiracy theory thinking, bordering on paranoid delusions[61] stating,
Clearly, GM waged a war on electric traction. It was indeed an all out assault, but by no means the single reason for the failure of rapid transit. Also, it is just as clear that actions and inactions by government contributed significantly to the elimination of electric traction."[62]"
