Eyefly, I will tell you, a professional driver would not dodge a pothole and endanger another life. Also, I see you are not knowledgeable about diesels. Leaving our engines running, ilding is the worst thing we can do for them, they are best shut off, running at rated under load, or using an APU or other means. We may all, be one as you suggest, yet I humbly suggest you take some further education courses. Take care.
