I have made it clear that I support restrictions on driving (including a ban on texting while driving), at the state level. Ny poinit is that the Federal government has no business getting involved in this.
...and my point is, that practically speaking, transportation cannot really be a state issue only. I wish it could. But it can’t due to the nature of transportation. You misapprehend the very nature of what the discussion is about. Certainly shipping and aviation are ludicrous to consider state issues. Are you really going to subdivide modes of transportation?
There are a very few things that are by nature a federal issue. I submit this is one of those very few things.
