That’s ‘congestion’ which really buries the lede, and who knows how they came to that figure or what they consider congestion.

The average commute in the US is 27.6 minutes one way.

https://www.census.gov/newsroom/press-releases/2021/one-way-travel-time-to-work-rises.html

27.6 x 2 = 55.2 (Assuming most return to  home)

50 weeks (assuming two weeks vacation) x 5 work days = 250 work days per year.

250 x 55.2= 13,800 minutes

13,800 ÷ 60 = 230 hours

Almost six work weeks worth of time, assuming a 40 hour work week.

Averages like this are misleading. The daily round trip average commute in the NYC metro area is 71.8 minutes.

RTO mandates are expensive both financially and mentally, and create significant unnecessary pollution and waste.
