My girlfriend go into an accident today, well rather she caused one. she was coming to an intersection that was green her way and didnt see the brake lights of the person infront of her and hit them, it sounds like from her description that she locked her wheels and slid, because she said that the brake pedal was down as hard as it would go but the car wouldnt stop. i know for a fact from doing the brakes on her car with her that the brakes are mechanically sound and do work. I also know that the cheap snip '$50 for all 4 installed' tires on that car will lock and slide in a hard stop. cheap snip tires like that shouldnt be road legal! She says shes fine, but she sounds really bummed about it.
