Cruise control is standard on the 123D, NOT on the 120d or 118d.
I'm not sure about the 125i.
I use it ALL THE TIME .... Even on smaller roads ... why?
Well, I've noticed a "bad driving" habit. I usually have the board computer set to the instantaneous milage/consumption. I have noticed that, even though I thought I was driving at constant speed, I was speeding up very gently, almost unnoticable. I have checked this by driving the same roads day in, day out, sometimes by giving gas myself, sometimes by using cruise control. When driving with cruise control, my instant mileage is about 1-2L/100km lower... Doesn't seem much, but when you drive constantly like this, your average goes up a lot. Being under 5l/100km or above, is a matter of just a few millimetres more on the pedal....
When I tried keeping this low mileage by giving gas myself, it felt like I was slowing down slighly, whereas in fact, I was keeping constant speed.
Is it only with this car, I don't know... first car I have with instant mileage ...
Just a comment from a neurotic gas-saver
.... I tend to make a game out of it
