How is it not a security threat and a risk and a privacy issue that people can see Uber drivers real-time?

Many responses here are only considering a case in a city setting where there are many cars on the road. What about in a rural area or during late hours where there aren't that many cars on the road?  Being able to identify when a car would drive by on what road may be useful information to a criminal.

Car hijacker or a robber can certainly wait, barricade a road, and stop the driver.

Let's take it a step further. What if a sexual predator would request a ride and keep requesting until he gets a female driver?  (in most states, he can see the driver's first name)  Then he would know where she is driving.  Cancel the request to have plausible deniability, and then attack her when she comes to the neighborhood.

What exactly would be the risk that people know where cars are driving?

Are there special reasons drivers would get targeted over other drivers out there? You know, those driving in plain sight.

I am trying hard to see this from your perspective, but I am not sure if I can. Putting aside the legality and such aside, let's think about how a criminal would be able to take advantage of this visibility.

A psycho would open his Uber app in his apartment. He sees 12 Uber drivers around him. He knows exactly where they are.  ...but now what? Run up to your car and attack? There has to be a reason they want to attack an Uber driver over many other cars that are on the road. These drivers aren't special, right?

Is there a female angle to this? 

First consider than an Uber driver would be a terrible choice for several reasons.  Not the least of which is that we DO NOT accept cash payments, and most seasoned drivers KNOW BETTER than to carry much cash.  Second many of us have defensive methods in our cars - far more than the average driver.  I would mace your eyes SO FAST!  Others I know have Concealed Carries.  Third, I see cars all around me all the time.  Being able to see them on a map certainly doesn't somehow make them more of a target IMO.  Having driven for Uber since they first arrive in our market (over 3 years) I am very happy to say i have had some questionable customers that may have been participating in some suspect activities, but I can only think of one trip where I felt slightly unsafe and that was a matter of where I had to stop and wait in a well known questionable neighborhood.  I have never felt threatened in any way thankfully.

Isn't the location of the vehicle the least of the problem? I mean, we work in a profession where anyone can literally SUMMON US to any location upon request.

I mean, there is not even a need for you to hunt us down.  We would literally come to your location.

I dont see how this would be an issue. Too many variables. The only way I could see this to be an issue is if you sit at your house waiting for request. Even then the person who plans to carry out a criminal activity would have to know some things about that driver to even plan any criminal activity. Many times cars look like they are on top of one another but yet the cars are blocks away from each other. I sit at a small airport on occasion. It will show 4 cars parked one after the other or on top of each other. Yet there are no cars visible to me. They are probably on the airport grounds but in looking at app we are all next to one another. 

I really do not see any issue with this. What is that one person who knows your lcoation going to do with the information? Keep following you and drive out to meet you and road block you in? all for what? To rob you? I dont know just seems really far fetched to me.

Don't you mean the passenger locations, maybe? I know females prefer that drivers not know where they live. That would be a security risk. Drivers? I suppose drivers can get robbed or something.

Perhaps taxi drivers used to get attacked because they carry cash (as they accept cash payments), but I am thinking Uber drivers not so much. For what they make, they'd be horrible targets to rob for cash.
