in the civic, the temp gauge pointer is calibrated to be flat line from 
85C to 100C.  that's a pretty broad range with zero needle movement, 
especially when you consider the thermostat starts opening at 78C and is 
fully open at 90C, and it makes any needle movement other than "hot" 
pretty much meaningless - "idiot light" territory.

while i "like" to have a gauge myself, engineering reality is that it 
doesn't mean much in this situation and an idiot light would probably be 
a better single choice if, like me, you just happen to be distracted and 
don't check the gauges and end up cooking the motor one day.  a light is 
much more noticeable.
