True - but for me this is what peaks my interest (obviously not a 
performance vehicle).  Numbers like torque required to maintain 
cruising speeds, effects of trailers, cargo and such.  More of an 
efficiency thing.  Some of the (very interesting) ideas on sensors 
for this application sound very worth trying, but I'm wondering about 
their linearity/accuracy at lower levels (say 10bhp cruising?)
