You forget that America is a car culture outside of NYC so a typical tourist coming to NYC for the day will likely just eat the cost and drive anyway. The geography of NYC is also very challenging. A lot of the public transportation options don't even cover places like Staten Island properly so people drive instead. There won't be much of a difference in traffic imo. Taking the train is already pretty expensive.

Maybe those tourists can do what this tourist did (well, my parents). Park at some station and take the train in.

It was the obvious thing to do for Europeans visiting a metropolis.

When you have a large group it's cheaper to take a vehicle in.
