I've had my 2016 P90D for a week or so now, and love all the new tech. However, the lane departure and blind spot warnings seem incredibly subtle. I assume it's a fault, but wanted to check. When I switch lanes without signalling, I can hear the vibration in the wheel, and if I really concentrate, I can just about separate the warning vibration in the wheel from the standard road vibration. My assumption is that it would be akin to driving over a rumble strip, and enough to catch my attention if I'm dozing off or texting. As it stands, I wouldn't notice it at all if I wasn't paying attention, which defeats the purpose. Just me? Time to book it in?
