Words like "tend to" and "less" are empty phrases. Individuals across the entirety of the income spectrum rely on vehicles, which is why there are literally as many vehicles on Vancouver Island as there are driving-age individuals.
The problem with these taxes, levies, surcharges or whatever you want to call them, is that they further segregate society between the haves and the have-nots. The measures are only effective at removing individuals on the lower end of the income spectrum from the equation while the behaviour of the haves continues on unabated, if not resulting in an increase due to changes in demand for road space.
Fees, surcharges and levies are not the all-lifting tide they are made out to be, and are, in reality, strong currents that widen societal schisms.
