I've once went through them when they first started rather faster than expected didn't get a ticket because they had forgotten to turn them on. But last time I've went through them at speeds varying between 30 and 40. But it works out the average speed you go. I'm not sure if the cruise control actually does true 40mph or in reality just a little bit below 40mph.
I think Cruise sets it at whatever actual speed you're doing, which is read out in km/h by my trip computer. The actual speedo needle seems to sit just below the actual figure.
See what happens anyway...
