We currently have 4 questions tagged cars.
We also have 2 questions tagged travel. One of those is also tagged cars, and the other mentions cars, so should have the cars tag if we decide to keep it.
However, do we need both cars and travel? It seems to me that any question involving cars implies travel. Is there a sufficient distinction to merit two separate tags?
If so, is cars what we want? What about trucks, boats, trains, etc.? I would prefer not to see separate tags for each of those, so if we need a tag to accomplish what cars is trying to do, perhaps we should reconsider the name?
