BS. Most cars drive on freeways and interstates most of the time, especially the large trucks etc. traffic in residential areas is generally pretty low and it more only during mornings and evenings.

This is just war on cars.

Cars are used only 5% of the time, the rest of the day most of them sit around. They sit around in the sun, heat up and only disperse this heat during the night. Without those massive metal blocks in our streets, instead of large trees, the air could stay cooler during the day and night.

Indeed. And those pesky metal and concrete office buildings sit there empty half the time soaking up heat as well. Not to mention the apartment buildings.

In fact, let's just get rid of the whole city all together. That'll solve the problem.

In a lot of US cities, freeways/state highways are where a lot of commercial, retail, and entertainment destinations exist. The first homes usually aren't that far away either, and a lot of apartment complexes are built directly on state highways.
