If you don't have a dash cam, buy one.
I've had two people now lie about fault, to me, and to the police. Video doesn't lie. It's saved me thousands of dollars in deductibles and ********, and who knows how much in my rates staying low.
Since people will ask, I have a A118-C. It's been great for years. Though I will be replacing it with a dual camera system to also record the rear. I think any is fine, but if you're somewhere hot, be sure to get a capacitor powered one.
