This is what is called inflammatory.

To legitimately compare the two, you’d have to combine all of the war deaths into one bar and use a set time frame, like others have noted.

Why? This isn’t making the statement cars cause more deaths than all wars, it’s saying it causes more deaths than specific wars. When people say Spanish flu caused more deaths than WWI or that COVID was killing more people a day than 9/11 you don’t turn that on it’s head and demand you compare the flu to all wars or COVID to all terrorist attacks. It’s just a metric to show the human cost of things, which makes a lot of sense to people who live in a market economy who want to put a price on everything. You can’t compare apples and oranges, you can compare the cost of apples and oranges though.

You have the granularity of individual wars yet the composite of all car/vehicle deaths (worldwide?) compared to each other. The chart just appeals to the abstract and doesn’t really offer much use other than to inflame the reader’s emotions.

Do you think statements like COVID was killing more people per day than 9/11 or that it has killed more people than WWII inflammatory?

If so is that a bad thing? A graph showing the amount of malnourished children in the u.s. would be very inflammatory to progressives, just as a chart showing the amount of immigrants entering the u.s. would be inflammatory to trump supporters. Factual agitprop isn’t objectively bad it’s just subjectively bad depending on what you think people should be angry about.

Subjectively you may disagree that car deaths are something to be angry about but objectively the graph is fine unless it’s false or misleading. Its not stating or implying that cars are more deadly than all wars combined, it’s stating that cars have killed more than some specific wars. Whether that fact makes you angry is up to you.
