Sure, but so what? If you ask me, I'd happy to increase property taxes AND toll highways at the same time to seriously boost public transit to a level that is way beyond what's being contemplated. That's just me, and I don't run the city. Besides, in case you want to frame it again as a fariness issue - driving (and by extension, being able to park downtown; or conversely, living downtown and driving out) is anything but - in the former, if you can afford parking, you can afford $2 each way; the latter, well you just pointed out that residential taxes are low - that would be one way to recoup it no?
