Not that odd. Death by car is easily accepted by society. They are "accidents" and a "necessary evil" for society to function.
There's around a million people dying from cars every year and we just shrug and normalize them. Human or not, we just have to have cars and "accidents" are just that.
According to the World Health Organization (WHO), road traffic injuries caused an estimated 1.35 million deaths worldwide in 2016. That is, one person is killed every 26 seconds on average.
Nobody cares about cars killing people and animals. So she's probably right.
