Nothing new to say here that hasn't already been said.
For the amount of time Presto took to roll-out, and the number of already successful contactless systems in the world, implementation of Presto is piss-poor. It is woefully lacking in what should be standard features of a contactless system.
It has the potential to be the most flexible, useful transit card, but that is all it is - potential.
Mismanagement and transit system politics will probably ensure this remains a half-assed platform.
And while this doesn't affect me directly, they will regret their decision in turnstyle design, if they have not already.
I keep tokens on me, just in case.
