The highway is a lie it is in fact not endless and there are not enough ramps to have fun on this map, the invisible walls prevent you from using a submarine on this map. The runway is not long enough for planes to take off.
Good map and the AI will chase you without getting too confused, however, be warned that it's just several miles long and not endless. I took the name a little too to heart and was flying like a bat outta hell at about 210 mph, saw what I thought might be sup kind of tunnel up ahead. As it got a bit closer...yeah yup...nope thats a f*cking wall!! O_O S**T!!!! SLAM
9/10 would pancake car again.
