How do drivers react to partisan bumper stickers?

I do think the conclusion makes sense, I'm just not sure about how well this demonstrates it.

I wonder why they didn't do the flip-side demographic experiment.

With a simulation you can help prepare someone to be able to react within a "situation". It does not follow that you can simulate a "situation" and extrapolate that a person will react and behave as they would in real life.

This experiment only involves simulated dashcam footage as the "experience". It does not include the visceral feeling of actually being in a car. I personally know that my mental processes whilst driving are not the same as when I am, say, walking a street. For example when in car mode I "know" that German marque cars often have ineffective indicators. I could go on at length and no doubt my own driving style pisses off someone. That is the way of the road and for some reason, touch wood, I've managed to keep safe for 30 odd years driving. The way of the road is not controlled for in the simulation described.

You might as well remove the driving "simulation" and simply ask people what they think of the partisan stickers - I suspect you'll get the same results.

I think social media became the outlet for all that stuff and the damage to the paint hurts the resale value of the car. If I ever see any stickers otherwise it's on the glass and still not political.

I think everyone kinda just admitted to themselves that they're trashy and pointless.
