I'd go with that.  My experience, particularly on the V8, is that the gauge 
goes up 
after a high-speed run, then comes down again if the speed increases again.  
Indicates that the cooling effect increases faster than the heating effect, at 
for 'normal' highway speeds.  I suspect that, the V8 in particular, would have 
cross-over at some point, the energy required (and hence heat generated) to 
push the 
car through the air increasing exponentially or whatever.
