Even though the political discussion when it comes to parking meters is mostly unheard of today, it's inclusion in the article draws the reader's attention to how parking and the costs of owning a car have changed over time. In general, I feel that this section of the article shows the effectiveness of incorporating historical events or records into an explanatory feature for the purpose of broadening a reader's perspective.
