Walking - We were given legs for a reason - So walking whenever possible. If it is a long distance I will use a teleporter sharing service, for instance UberPort, we have many booths here in the city, you have to walk to them first though !
I'm surprised "Plane" did not win the votes. It is one of the safest methods of transportation - unfortunately the downside is the close proximity to unruly passengers, but otherwise it is the safest, given reckless drivers, road rage, etc, your odds of being in an accident are very high. The next common option here is public transit, it's not as bad as planes as you are not stuck like sardines, but you are still in proximity to mostly crazy people, drunks and drug addicts
Oh yeah when all UberPorts are taken, my 2nd favourite method of transportation is FlyingCarpet, I don't own one, but usually those are available here for rent, it's cheaper than a taxi or Uber and at least you get to enjoy the scenery whilst traveling !
