In 2021, there were the most motorcycle fatalities since records were collected in the mid 1970s at 6,084. Compared to 26,585 passenger car fatalities the same year. So at the statistical peak, there were still ~4.37 car fatalities for every 1 motorcycle fatality.
You’re likely thinking about the rate of deaths per 100,000 vehicles which is much higher for motorcycles than cars.
Look at any road, anywhere, any time of day, any time of year and you will see way more cars than motorcycles. There simply aren’t enough motorcycle on the road to account for more fatalities than cars.
