I took a taxi to the airport in Portugal yesterday. The speed limit on the road was between 80 and 120. The taxi driver was so interested in talking to me, face to face, I didn't have the heart to mention the fact that he was driving at 180 most of the time. In fact the only time I saw 2 digits on the speedometer was when he drove through the toll gates, clearly marked 30, at 90.:)
If anyone is interested. I have the phone number of a very good taxi driver in Lisabon, Portugal, that will get you quickly to your destination, and that for an inexpensive prefixed price.
