While the idea of cruise control maintaining a constant MPG is a worthwhile cause, it will really create problems for us. I am sure with the great minds we have here we can develop and test a functioning bench test model, but here are my concerns.
I use CC everyday on my commute, in fact it is the only way I can maintain the high mileage averages I get. This gives me time to monitor the
scangauge reading during my commute. I notice that my instant MPG fluctuate continuously throughout a range of about 7mpg due to traffic, wind conditions and the most obvious road elevation. Those small changes in MPG's would crash any computer trying to determine how to react so quickly to those changes.
Instead, I feel the CC should have a P&G mode utilizing they latest technology in order to sense distance ahead of it in order to avoid accidents while doing P&G or even simple locked CC. Including a logic for hill climbing and simulated EOC would be icing on the cake, but it would take one of us on the inside to convince auto manufacturers to pay so much attention to something percieved to only be used on long trips to Wally World.
