Noticing less traffic?

A study has found that there is less congestion in U.S. metropolitan areas. Have you noticed any difference here? 

"The National Traffic Scorecard cites two main causes for the drop in traffic: volatile fuel prices and the economic crisis. However, the company notes that congestion was basically the same during the first half of the year, when gas prices were high (and the financial situation seemed fine), compared with the second half of the year when the economy experienced a precipitous slowdown and gas prices were low. So one might surmise that when people have to drive, they are going to drive no matter what the price of gas is. On the other hand, when you don’t have a job, then you don’t have to commute."

But Chicago is still in the top 5 of worst cities for commuting.
