> Yes, people who can't afford spending $15. Anyone else will continue as they do, as private transport is safer, quicker and more convenient - plus there will be better traffic, as the poor will be taken off the road.
This isn't true most of the time is quicker to take public transportation due to the congestion issues. Cars don't scale.
> How is that going to do that? If someone is affluent, I don't think they are going to think twice about spending $15 extra. It will discourage people who cannot afford it.
Yes the point is to discourage people from driving into Lower Manhattan. Lower Manhattan is easily accessible by public transportation.
> Poverty is relative. Someone may be compensated well enough to afford rent, parking and all that, but after paying everything they have little money left for themselves. That $15 may eat into this meaning you may reconsider whatever arrangement you have - effectively pricing you out.
The poverty rate for NYC is $35,000 if someone can afford to pay $24,000 yearly in parking I doubt they're in poverty, especially when public transportation is available and is quicker due to the high congestion. This wouldn't be implemented if there wasn't an alternative.
