In my old '88 3.2L it was really, really easy to see 125-130 around the area on deserted roads. It doesn't take very long to get there if you are already doing 50-70, and the roads around here are generally very long, very straight and very flat. On the way to Dallas once up 45 I saw about 145. On the way back from visiting my parents in the panhandle of FL on I-10 westbound in AL or MS I saw 150 (based on rpms not speedo).

But as stated, only when there are no other cars in front visible, only when you can stop in the distance you can see ahead, and only when there is no where for another car to come from in front of you.
