If you want to see mob involvement related to cars you want to look at the towing industry, but generally they stick to the money, which is construction.
There are also companies going after Uber's model but with strong ethics, such as Teo, which seems to be widely praised (good app, fully electric cars, good conditions for drivers, wifi inside the cabs).
My main annoyance against the taxi industry is its lobby, which is always against any sort of change in the transportation industry, such as new train lines (airport train or bus line), bike/bixi ride-share, etc. Taxis and Uber-type systems offer more transport solutions that reduce the requirement of having a car. I would love to get rid of my car, but it's not viable in Montreal (I bike to work, use the car mostly on weekends and Communauto requires me to do too much planning).
Not quite organized crime, but not far from it!

It's Montreal. They couldn't organize crime if they tried.
