Met an Audi driver today

So I drove from a Salem to Bangalore and on the way I saw a Audi Sedan (KL) driven just below the speed limit. I gave him lots of space to overtake but didn't change lanes nor overtook much vehicles. He would only speed up only if a cluster was forming. I would overtake him when him when he was stuck behind a truck or he would overtake me when I was behind slow moving vehicles. this happened to almost 150km so we kept passing eachother. We both ended at the same rest stop. I had my coffee and i went up to him and complimented him on his driving. He replied that he drives between 70-80 only to get the maximum mileage. He was a businessman and was heading to pick up his family in Bangalore and then headed to Kerala. A real gentelman.
