For any tourist thinking of coming to Portugal, beware. I took a ride from a friend that does touristic tours - he's no uber or whatever, he speaks many languages and is an historian doing cultural trips in Lisbon and Algarve. Today I noticed several taxis cutting close in front of my friend's car. Trying to cause an accident on purpose, while mean mugging us on the lights. I know taxi drivers are simple people and don't respect competition, but my friends is not an uber like... Avoid getting common taxi. Download any other ride app, because these actions are so common it only took me one single ride to really understand the ridiculousness of the situation. The taxi club - or whatever administrate then has to take action. All taxis today that did stupid manouvers on purpose, some above speed limits, had customers inside!! Thanks
