Citing Roth approvingly might alarm some readers who dislike neoliberal ideology (also known as 'economic rationalism', 'economic liberalism' or 'economic libertarianism' among others).
Roth was actually a key intellectual forerunner of Donald Shoup's thinking on parking. But it may be hard for some of you to think about this with an open mind since Roth was and is quite right-wing in his ideas on transport. He is better known for his later advocacy of public transport privatization and deregulation and for his ideas on private roads.
I don't share many of his views on those issues but I do think Roth's parking policy ideas were promising. Sadly they were largely ignored (as far as I know) until the recent upsurge in interest in Donald Shoup's proposals.
For anyone on the left of the political spectrum it may be very hard to keep an open mind to ideas that came from someone like Roth and were published by an outfit like the Institute of Economic Affairs, which is a UK 'free market' think tank. It played an important role in the rise of neoliberal policy ideas in the 1970s.
By the way, my Transport Reviews paper on parking (journal paywall version; earlier pre-print version PDF) expressed surprise that a neoliberal thinker like Roth actually stopped short of advocating complete parking supply deregulation, as Shoup does.
