You're going to have to be more specific about what "it" is that "seems to be subscribe". Do you mean publish? Additionally, there are many ways to generate output in vehicle_cmd. You'll have to give us the list of nodes that you are running. An rqt_graph while you're running your stack would be even more helpful.

both published and subscribed topics list show the vehicle_cmd however when I try to print info from vehicle_cmd it states 0 0.0 . I could send you screenshot details not sure how to put them in here.

You seem unhappy it is 0 0 0. What do you think it should be?

OK, we're making progress. You're not sure what is supposed to publish to that topic to make the car go? Why don't you provide more information about what you're trying to do, as suggested above by Josh?

Yes. I want to get autoware setup so the vehicle drives the demo route as it should be. As currently it doesn't as I suspect maybe the launch files aren't setting everything properly.
