I've never taken Lyft or Uber, but are the drivers required to go where their GPS tells them? Or do they just not know the route?

Being used to traditional taxis myself, I find the need for these full-time drivers to be so dependent on GPS a bit surprising.

It's a suggestion, but if the driver takes a longer route and the customer complaints, it will impact the driver's rating (and earnings). Learned it the hard way after an UberX driver tried to get onto a bridge with tons of "Under Construction" signs, as his GPS wasn't aware the bridge was being repaired.
