I don't think that's the kind of thing we can have a direct study of. Nobody is going to send children out into the streets to see how they fare and we don't have numbers of how often kids run into the street because nobody is there recording that.

Wikipedia[1] shows deaths per 100k vehicles per year. It puts the US at 14 compared to China's 104. A slightly better statistic would be deaths per billion kilometers traveled but that's not reported for China.

If I had to bet, I'd bet that there is marginal benefit from having lots of experience with children running out in front of you. Maybe there's a slightly higher chance per incident of child-street-running resulting in death in the US, but I don't think there's any evidence for that opinion.
