cruise is a really useful option and i loved it on my old beeza.
Although BMW cruise is a lot better due to the resume button, or as i call it the knightrider button.
The Mini's party trick is as follows:
Cruise at 80 mph in top gear, go through roadworkd and slow using brakes to 40 all the way through, as soon as brakes touched cruise goes to stand by mode, wait till national speed limit sign, leave in 3rd gear, press RES ( resume ) button and hold on, car acclerates flat out and a lot harder than throttle pedal to get you back up to 80mph. very fun, but does not work in second DOH!
can also cause accidents if accidently triggered.
