Regarding pedestrian infrastructure. That is just outright false, at least for Austria. Pedestrian infrastructure in big cities has improved substantially and even in rural regions many communities have made improvements. Many of these projects happened also after 2009.
That said, the rise of oversized trucks is likely the bigger factor here. When I was visiting the US in 2010, it was not half as bad as it appears to be now.

Paris and Vienna certainly had a lot going on in this regard since 2009. (Brussels too) I am not talking about the odd pedestrianisation.
A lot of streets have been redesigned, that has often benefitted both, pedestrians and cyclists and added more greenery and trees.
