Driving on the open road

[BF-2K7]

my choice of words may not have been what you actually said , but it was implied from the 'open throttle' remark and I took that to task, my appologies for not quoting you correctly

However ............ "but if you are climbing a long steep hill for example the cruise will attempt to maintain your set speed no matter what."

Most competant drivers would have disengaged the cruise control when negotiating a 'steep' hill (which you didnt mention in your post) Cruise control is not meant for steep hilly terrain however on gentle inclines and rolling hills it will perform I think better than 'human' driving as it will give only what it needs to get over the terrain whereas human input may push the throttle down too soon or too late therefore upping your fuel comsumption

The 'stomping' as an example of 'human' driving and that cruise control would not do this - and is a relevant point (maybe not to your post) however considering we are discussing the pros & cons of using cruise control I think it is.

I did a round trip of some 2176km up the east coast and my fuel economy (having a dedicated LPG ute towing a trailer) was excellent running an average of 14 - 16 kms/100l all done on cruise control on the highway/freeway - I did not use it in built up areas (such as around town) as that is not appropriate

Coasting and gentle accelleration is what cruise control does - once again I beg to differ on your belief that a human input gives better economy/performance than cruise control and will not be convinced otherwise as the human factor is too ambiguous with too many variables
