According to Airi, she has dashcams covering the front, back, and both sides of her car, and the accidents almost always get determined to be the other person's fault. If we assume both Airi and the other Phase girls are telling the truth, that means:
1) Airi is a bad enough driver to scare her passengers
2) There's a large enough percentage of even worse drivers on the road that even someone who drives like Airi isn't likely to be at fault in an accident
