Real traffic conditions aren't that simple, however. In a typical Portland cab ride, you'll deal with stop-and-go traffic. To deal with stop-and-go traffic, taxi meters merge calculations from both the time and the distance sensors, counting whichever pulse -- time or distance -- arrives first. So, if you wait 30 seconds in traffic and then cover two blocks in Portland, the taxi meter will merge the two and add 50 cents to the fare: 25 cents for the distance traveled and 25 cents for the time spent waiting. All in all; this could add significantly to your taxi cab fare. Go with My Chauffeur for great savings!
