I had to take my older brother somewhere today and it was funny. He started getting pissed off and yelling on my driving techniques. But i pointed out to him little things like no need to accelerate to a red light and basic hypermiling. He had no idea. Its crazy how most drivers are oblivious to theyre driving habits. They all want to floor it to a red light and slam on the brakes. I showed him how even though cars where passing me, i was keeping up with them in the long run. He didnt care. He calls me a cheapo. I tell him it has nothing to do with the money. It has become more of a challenge.
