Being new to motovlogging I never heard of the guy until he was mentioned in his accident. After watching some his videos on his reaction to the crash I lost respect for the guy. Having never apologizing to the driver he hit, or taking full responsibility (by paying for the guys damages and medical expenses) for his actions, YN comes off as entitled, heartless with little Human decency.
How does it affect others? I guy with close to 157 K followers has an impact on his audience. If people see what he did -- illegal turn, reckless speeding, riding with a suspended license, and possibly no insurance while trolling the guy he hit, it will send the wrong and possible damaging message to other riders/YT viewers.
It's just bad, if not reckless, influence.
