335i xDrive Cruise Control
I drive my 2013 335i xDrive the length of Interstate 89 several times a year between Boston and Montreal. I generally set the cruise control at 72 or 73 mph, a little faster than the limit but hopefully not enough to attract attention. On certain long steeper downhills, the car needs to slow down faster than coasting would allow in order to maintain the set speed. Question: Do the brake lights come on? If the car's speed was being manually controlled, they would light up.
