Mine has one of those, but other than testing to prove it works, I
don't use it. I rely upon cruise to hold my speed and being a manual,
it hold the set speed fairly well.


You mean "being a manual it holds the set speed less well than an auto".


Why should that be? I've only ever driven one auto with cruise control -
and that was a hire car in Australia. That behaved in a very peculiar
and erratic way. If you started to go up a hill, it would open the
throttle to try to maintain speed - often resulting in kicking down to
the next gear, whereupon it would accelerate rapidly - exceeding the set
speed - and then promptly shut the throttle and change up again - only
for the same gear hunting process to keep repeating.

Well obviously Rod Speed had been at it.

The Freelander will hunt a little when cold, but once warm its spot on.
Hard acceleration gradually easing off as it gets to the correct speed.

Its a matter of proper programming.



At least with a manual, *you* choose the gear and the cruise control
only has one parameter to control. Obviously, if it can't maintain the
chosen speed in the current gear even by using full throttle, you'll
need to give it a bit of help - but that's preferable to having an auto
thrashing the gears willy nilly!

Modern boxes and modern cruise control is better than that.
