Grog, glad to hear that you are okay. I tend to agree with those who recommend filing a police report. I know you said that you weren't injured, but there is always a chance that something may start bothering you several days down the road. A police report would be supportive in case you ever needed medical treatment at some point.
I live in Ontario, not B.C. so I don't know about filing a report post-accident, but I'm sure it wouldn't be the first time they've (police department) seen that!
