Lane keeping assistance over corrected and caused an accident that resulted in total loss of my vehicle. My tire crossed white line , I was trying to gradually adjust to keep from over correcting. The lane keeping assistance caused the steering to pull in the opposite direction and would not allow me to correct. The more I tried to get back in the lane the harder the lane assistance pulled in the oppposite direction. It ultimatley jerked the steeing wheel in the opposite direction a caused me to hit a tree head on.
