I understand your point in this instance, but do we really want large corporations choosing which municipal laws they can ignore? Shredding and delivery trucks already jam up downtown roads, accepting tickets as a cost of business. If food trucks can ignore by-laws on location, then why not on food safety? Can developers or renovation contractors ignore bylaws they feel are silly?
The city has provided Car2Go parking in GreenP lots across the city. It's not as if the company isn't being heard and accommodated by the city. IMO it's not the same as Uber, which is essentially a tool to let me share my car with someone else. Instead, Car2Go is a car rental corporation, not a service, akin to AVIS, Hertz, etc, but in this case using the city's infrastructure as part of their business, without that city's permission. If I open a moving truck service tomorrow, such as

Honestly, the easy fix to shredders, couriers, car rental firms, etc. from illegal parking is not tickets at all, but disabling the vehicle.
