I was coming home from work the other day and this S4 pulls up beside be, revs it a few times then takes off. I haven't tested out the Apten yet so I figured, WTH.. He wouldnt slow down so I'm going 80-90 the whole time just to keep up, then he slows down to about 65-70. I get beside him, look over and he knods and takes off. I shifted down to 3rd and hammered it.. The traction control light came on :rockon: and put BUSLENGTHS on him from about 70-130.... He stayed pretty far back after that.. :shrug:
