I was driving to my girlfriends minding my business when this g35 comes flying past me when leaving a red light but I think nothing of it until he slows down and gets next to me and takes off again. so I follow him and we get an open road going about 35-40 and I drop it into second. I hear him do the same then he hits it but i was ready for him. I hit just as soon as he does and I put about half car on him. I hit 3rd and now have alil over a car on him and I hold him there until about 90-100 before we ran into traffic. I never ran one before and I know nothing of these but it did surprise me I didn't think they were that quick.
