I'm told the SE has the coffee cup feature, but I've never seen it. It's true that if I belt down the motorway at full tilt I probably won't be driving for much more than two hours before I have to stop anyway, less in winter, but I've had several situations where pressure of traffic has meant that I've been driving for nearly four hours and it still didn't activate.
Once was travelling from Brighton to Halifax and the holdups on first the M25 and then the M1 were unreal. The M1 was particularly stressful because the lanes were narrow and the TJA assist didn't like it. I was going so slowly that when I got to my planned stop (Milton Keynes I think) I still had quite a lot of charge left. I briefly considered going on, but then I thought, you've been driving for three and three quarter hours and you're starving, just stop.
Another time I was driving from home to Fort William, which is about 150 miles, and again road works around Crianlarich and then heavy traffic in the Glen Coe area held me up a lot. I was just minutes off the four hour mark when I pulled into the supercharger site at Fort William. Never a sight of the coffee cup either time.
I checked the settings but nothing is turned off. It might be that it's simply inoperable on my car, I don't know.
