And why aren't truck tested as they should, hauling stuff? What's the point of driving a truck around town and saying it's fine? It's pointless. Attach a 6000+lbs trailer, drive around town for a while, take note of fuel economy, then try to merge onto the highway to test its acceleration under load and cruise at 100kph for a while. Take note of fuel economy again. Why are these trucks tested as commuter cars?
