So, "otthon" can only mean "at home," not "[towards] home"? It's not a directional adverb, right? Only a positional one?
Perhaps it means the idea of driving on holiday for example, but not at home - home in the sense of where you are from rather that house?
I am having a hard time with the use of "drive at home." I thought one only drives to and from the home. Does this mean they drive a four-wheeler around their property....or a golf or a go-kart?
Think about your home town. When I am in New York, I am home. I don't drive at home. I only drive when I am on a trip.
The another meaning of the verb "vezet" is "to rule". This sentence may means: I do not rule at home.
