Changes since congestion pricing started in New York

Hi from London:

The centre is much more pleasant to walk in, as are most places in the zone.

Pollution is much, much better: if you came to London and travelled on the underground you would have black snot when you blew your nose, this hasn't been the case for a few years now.

I hope NY gets the sake improvements.

London has changed for the better for sure but black snot on the tube hasn't changed at all. I get it from 20 minutes on any deep line like the Victoria. It's from train brake dust, nothing to do with vehicle emissions.

Victoria might be one of the worst for this. You can hear the wheels screaming the abrasion off for long sections of it. It’ll be interesting to see whether the Piccadilly gets better for you when the new trains arrive over the next couple of years.
