I was the first car at a light, in the right lane, and the Nissan was first in the left lane. I didn't even notice him at first. The light turned green and like I usually do, I took off pretty fast. That's when I noticed him trying to race. So I kept it up. We were neck and neck until we were over 100mph. At that point the road was curving and I backed down. I don't know much about that Nissan, but I was surprised it was so fast.
