I was driving in the left lane of the highway. Just up ahead I saw something sitting on the guardrail to my left which was jutting into my lane, right about eye level. It looked like a long wood 2x4. I swerved to my right to avoid hitting the piece (scared it would shatter my windshield) and the steer correct safety feature (probably wrong term) quickly threw me back to the left and into the guardrail. I turned my steering wheel to the right to get away from the guardrail and it threw me back into the guardrail. It did this a few times. I didnât understand what was going on. It felt like I had no control over the car. It just kept slamming back into the guardrail. I finally took my foot off the gas and it slowed down and stopped throwing me around. Luckily, there was no one next to me and no one else in the car with me. No one got hurt. If it wasnât for that âsafetyâ feature, my car wouldnât have been damaged. I did call the police to let them know about the wood piece that was sitting on the guardrail so hopefully it gets removed and no one gets hurt.
