Downvoting because the visual metaphors within the meme are inaccurate.
The train is "inevitability".
The bus is "society" or "populace".
"the 20-year streak of measles being eliminated in the us" is the road.
"anti-vaxxers" is this particular bus driver who decided to park the bus on the crossing; I assume they're sitting in the bus too.
..so, while all the elements of what you wish to communicate are here in the photo, it makes for a clumsy metaphor because the focus of the photo is the train and the bus stopped on the crossing, not the road and the driver.
“the 20-year streak of measles being eliminated in the us” is the road.
You are wrong, it would be the point of impact according to your method of marking. Also the streak itself is not signified by the road but the people alive already in the bus, again according to your logic. As The Quuuuuill mentioned, "The meme is flexible. Your attitude is not"
