&gt; This machine will keep pace with traffic. OK. Does that mean it will break speed limits?<p>If the highway speed limit is 55 and everybody is going 70, you&#x27;ll make the road a more dangerous place by going 55. I don&#x27;t know how it works from a legal standpoint, but from a practicality and safety standpoint, I&#x27;d rather go with the flow.
