Hi A,

That's a good question!

From my experience, one of the most difficult questions candidates struggle with is to estimate the impact of traffic jams  in New York.

Bear in mind that in interviews for MBB market sizing is just one of the part of a case interview (you have structure, graph analysis, brainstorming and recommendation as well). 
On the other hand, if you prepare for consultancies at BIG4, solving solely market sizing cases will help you.

All the best,
Egor
