I was on 101N at Gilroy. I had just merged on to the highway and was on the lane next to the rightmost lane. Within few mins and huge car came and crashed into my Tesla model 3 from the rear right side. He was driving so fast that I completely lost control and drove all the way diagonally towards the left and hit a wired fence on the highway. The other driver fled the scene. Unfortunately all my dash cam videos are corrupted. I tried really hard to re-cover them but in vain. The car is badly damaged. It's a 2017 model. It's being taken to the body shop now but I feel it will be totaled
