The ease of the truck moving through the city with less traffic and easier parking would have more than made up for the toll cost. Same for taxis where the cost compared to the increased demand (since the taxi might actually be faster than it would be now in midtown during the day) also probably would have benefited taxis and their customers.
Not true, you cannot simultaneously have lower congestion and higher demand for taxi. This is contradictory statement.
In the end not much will change, people who would have takes transit will end up takin transit, people who have to drive will drive, they just will pay additional tax.
