This inspired me to Google for the only thing that rarely annoys me about my M235i (touch wood), the rolling stop/go engine response. Say you're coming up to an empty junction, you slow to check each direction, maybe less than 5mph to give each way a proper double check before you head out. But when you hit the throttle next it can take a half to 1 second before you get any go. It may not sound like much but it feels like an eternity and really doesn't inspire confidence that if you did misjudge a situation and needed to make a more urgent getaway it won't deliver. It seems like there are mixed reports from others with exactly this issue, some people saying to drive in Sport all the time or Sport+, or fiddle with the DTC/DSC. Sometimes you want comfort mode and safety computers on though..
