I took a look of the video the of the crash. I didn’t see anything that suggested malicious intent to whack the cyclists. If they can charge spectators for causing bad crashes, charging race participants isn’t far behind
Malicious intent is not required in order to be charged and convicted of a crime. Extreme recklessness is sufficient. Consider a driver who gets crazy drunk and then causes a crash that kills someone. The driver had no malicious intent, but engaged in behavior that was so reckless that death or injury of others was likely to occur. That driver would be looking at a manslaughter charge at minimum.
