You might be right; that's something I haven't given a lot of thought to. The taxi industry is rallying hard to kill the Uber/Lyft's of the world, and while they're not winning in general, they're still putting up a hell of a fight and winning occasional battles. Once the automotive industry is motivated to join forces with them to prevent a decline in car sales, that might be enough political pressure to stop the whole thing. At least for a while.
