There is no reason that another car should ever have to slam on their brakes just because you want to jockey one car length ahead of them. Most folks drive at what they perceive to be a comfortable and safe distance behind the car in front of them. If you decide to cut in front of them where they have to reduce their speed for you...you are the jerk. If you really need to be in that lane, wait for a reasonable gap...or get in that lane far enough in advance...and wait your turn like everyone else..and courteously use your signal like other mere mortals. Driving a unique car just makes you stand out even more as a jerk. No wonder so many think Porsche drivers are pricks! Don't ruin it for the rest of us that drive like adults.
