That is a fairly strong claim on the surface and the company's website has a slightly different one:
"In 1964, Jean-Claude Decaux invented advertising street furniture."
Such a fundamental mistake in the opening paragraph. Made me realize I could not trust whatever was written afterwards.
touristy track is covered by cctvs and they are used to get people for anything including public urination or graffiti so of course it's clean
I wish the touristy places in the UK were as clean though.
Also, writing this comment on a crowded, dirty and smelly train from Gatwick Airport, which has 2 carriages inaccessible because of broken doors and crawling due to signal failure on the line, I already miss the clean and comfortable Chinese trains I was taking from place to place.
That said I do get to work 945 here for more money so I am grateful for this for sure. :)
Uncorrelated with the usefulness of the building after controlling for other factors
I gather locals who drive are in violent disagreement with me on this, and Paris is a big place that extends well beyond the posh touristy arrondissements, but it's still remarkable -- especially given that the downtowns of most American big cities have gone downhill in the same time period.
LA Metro has a mere 120 miles of track vs Paris's 150 miles, but in our defense they had a 90 year head start :)
