While the use-cases for cruise control are more limited with a manual transmission, I wouldn't go as far as to say the two are incompatible. I would never use it in heavy-traffic and rarely on a single-carriageway (i.e. anywhere that travelling at 60+ mph is a hazard), but if you're only switching between 4th and 5th, then it really is very useful I don't know of anyone that uses ACC for city driving or non-motorway commute. This might be due to the nature of British roads, though
