The way I see it, they are paying for the privilege of sitting in a motor vehicle that they don't have to share with anybody and the only effort is to push on the brakes and accelerator pedals. (And yes, for some, the clutch pedal.) I won't go into how I pay the same amount they do to keep my car on the road, because some ppl don't own cars, and they have as much right to the road as car owners, if not more so, since they don't cause any damage.
This is actually a positive thing. At least this person is putting their thoughts out there where others can see it and can take them to task for it.
