It's even better when it's done in a different colour. Then it makes it really clear that the freeway is wider than the 3 parking that abut it on the left.
A lot of the time, there are minimum parking requirements - e.g. a mall is required by law to have enough parking for their busiest day of the year. So the other 364 days of the year, guess what happens...
That color scheme is really hard for my color blind eyes to see, since the orange (?) and green blend together, but dang, what a fucking statement it makes! Just imagine what could be there if people weren't driving. Amazing visual.
Assuming the random dafa I got off the internet is true, 5% of the US is covered by parking and the area of the US is 2.4 billion acres, digging these fucking things up and planting trees could sequester about a billion tons of CO2 per year (while, you know, preventing billions of tons from cars). Making all surface parking in to parks with grass and trees could sequester about 6 billion tons per year.
CityNerd's maps tend to be much prettier than this (not trying to throw shade, I would literally do much worse than this) and lately, he's just be using this instead of making his own.
