I witnessed a taxi from Nu Liberty Taxi today, 12/10/13, entering I-5 from the airport in a very unsafe and aggressive manner. It was taxi #16 who with his selfish driving endangered several other vehicles and had absolutely NO regard to the other vehicles on the road. It wasn't only his merging onto the freeway, from the merge lane straight to the fast lane, cutting off at least 2 vehicles (one of which was an 18 wheeler) he continued to drive erratically with numerous lane changes, excessive speed and in my opinion a total lack of regard to anyone else on the road. I pity the passenger. I contacted the office to be told by the driver who answered he didn't know the office manager or person of authorities name. When he told me, prior to my mentioning the taxi in question, he was driving #16, he refused to continue the conversation and hung up on me. Makes me wonder what type of license and standards this company maintains or possibly he lied the entire time and he was the owner and driver. Guess I will contact the better business bureau as this is a route I travel frequently.
