The MTA is finally addressing the tragedy that is moving between subway cars. 
Now if I paid attention to the report as I heard it on the cab radio (which of course I didn't) the fine will be $70 for moving from one car to another while the train is in motion. The accused will not be fined; however, if the move is done so that one can avoid an offensive odor no ticket will be written.
Which is totally subjective. Will excessive use of Clinique Happy or Davidoff Cool Water (or any 'layered' fragrance) be included? What about excessive old-people smell? The smell of odd hair product?
Why is smell the only sense allowed offense? What about hearing an overloud baby? Seeing too much pink on body types that don't support it well? Touching a piece of flesh that is just too chunky? And of course the sense of taste. What if you just know, in your heart of hearts, that there are simply people that are more in tune with your sense of taste in the next car.
Luckily, the rules don't go into effect until October 1 so there is time for necessary modifications.
