Good try, but...
China has (according to the
figures I can
find) 8 cars per 1000 inhabitants; 9.6 million cars. The US has 940 cars per 1000 inhabitants; 283 million cars. So your figures aren't just wrong, they're out by more than an order of magnitude. Every year, there are between 110,000 and 250,000 people killed on China's roads, depending on whether you believe the Chinese authorities or independent organisations like the World Health organisation. Let's take an average: 180,000. The US, by comparison, has an annual road toll of around 40,000.
So, by whatever measure you use, the US's record is massively better than China's. One death per 7075 cars in the US, versus one death per 53 cars in China. One death per 7500 individuals in the US versus one death per 7343 individuals in China. The usual measure of road toll, though, is fatalities per million km driven. China doesn't publish this information, but I think it's safe to assume the number of kms driven in China is massively less than in the US.
Still not scientific, but - sorry to say - a crap load more so than your effort.
