I use to have a yellow car. I think the less accidents is because drivers of yellow cars have to be more vigilant. The number of people who would just pull out in front of me when driving the yellow car as opposed to the other car I had, which was white, was ridiculous.

A van owner once mentioned that no matter how fast they drove, people acted like it was moving slowly. It looks slow.

I'll bet red and yellow cars get a safety boost the same way: humans are morons and assume they're hauling ass.

Boomers and GenXers used to love red cars because anyone driving a pov-pack Hyundai Excel in red thought they were driving a Ferrari.

There used to be a meme (idea) that red cars were cop-magnets because people in red cars would drive like dickheads.

All those Boomers grew old and started buying Maroon cars because they were technically red, but wouldn’t be cop-magnets. These colours are colloquially called “Old-Man Burgundy” or “Haemorrhoid Brown”.

In the UK, the fronts of most/all trains are painted yellow for this reason. Given that cars are more abundant and less predictable than trains, perhaps making them (or just the bumpers/trim) yellow/orange would have safety benefits.

That's interesting. I'm also remembering an I don't know how old study that indicated that red cars were ticketed for speeding the most amongst all colors.
