I think this was tried in the US a very long time ago. Not as a law but as a limited experiment. I do not remember much, but I think it was abandoned due to a couple of safety issues. One I can think of is long steep down hills with a large truck in back of you. Cases could exist were you could not get out of the way and you cannot speed up. I do not remember the details. In many places in the US, this scenario does exist.
