The place I worked a few years back had a Idiot as a Transport Clerk, it was in his mind we could do our depot in Birmingham in 2. 1/2 hrs from our Lancs Depot, I said many times I will get there when I get there, as said, a lot of people may think the short Journey could take 20mins, it may well be, "But What If" that's the way I used to think about Journeys, "What If" 2 drivers are not alike, drivers think other drivers are like them, they may be Positive, others are very unsure in their motives, you will never get a patient driver no matter what you think, the main trouble, a driver think he / she will get there quicker by flying, you can think what you like, it does not work like that.
