How can you tell someone hasn't taken useful and serious drivers education? They don't understand why the driver is positioned as they are in a car/truck/etc.
A driving trick: Most passenger cars have a hood. If you find the center point of the front of the hood, and sight down that, you find the point on the road where your outer wheels will track. So set the edge of the road along that sight line, and you're safely driving at the edge of the road. Few exceptions. It is true despite the apparent design differences among various makes and models.
You learn that from serious driver ed instructors.
