It's a little unclear what Lyft's response to the driver actually was. One article ( from heavy.com ) says that "Lyft continued to allow this driver to continue driving for Lyft under a different name", which suggests the possibility that the driver may have been suspended and re-registered under a psuedonym. The implication is that this is fine by Lyft, which is unclear.
Please don't take me as being unsympathetic, I certainly am not. Here's some food for thought: If you were falsely accused of a crime of this nature, heaven forbid, your life pretty much depends on you receiving the full due process of the law granted to you by your rights as a citizen. Cases like this can take years of litigation to resolve, which is very unfortunate. This is not because the legal system does not care about women, it's because the legal system cares about the rights of the accused. Unfortunately sometimes this can mean guilty people being able to fall through the cracks, but if you can think of a better system for guaranteeing individual rights we'd all like to know. Until proven guilty you are presumed innocent. Unless remanded to custody, you are free to go about your life in the meantime. If you were fired from your job at the first hint of accusation, the ramifications for you as an individual could be very severe.
In this case it sounds like the driver was guilty. However, I'd advise you and many other people to resist the urge for lynchings, kangaroo courts and witch-trials.
