Interesting link. Thanks for posting.Will be interesting to see whether it backfires:
A Fine is a Price by Uri Gneezy, Aldo Rustichini :: SSRN

My read from the research study was that they had a fixed fine for being late which was viewed by parents as more lenient than the societal construct of showing up on time -- i.e. it legitimized the behavior and just turned it into a price (as the title suggests).
I'd be surprised if the same reversal of incentives held in the Supercharger case, as users will be charged per minute, at a rate of $24/hour.
A rate of that magnitude will obviously end overnight parking, and should greatly deter extended parking (1 hr+) as you'll quickly exceed the cost of a gasoline fill-up.
I think what Tesla is doing will have the effect they anticipate. The per-minute rate is the key deterrent.
