Bad bad things.
I've had my Tesla on a highway either lose GPS precision and believe I was on an adjacent local road..
It immediately reduced speed from 60mph to 25mph .. aggressively.
This falls into a pattern of Tesla autopilot/NoA where it just doesn't seem to have much memory or foresight.
For example the car is driving itself on the highway, it knows it's been on the highway, for 20 minutes. I am not even in the exit lane, it knows what lane I am in. How could it think I am suddenly on the local road below the highway based solely on the GPS pin movement in the span of a second, without having moved to the exit lane and gone down the exit ramp?
For an example of lack of foresight - the car will happily speed towards an obvious semi-distant slowdown right until it needs to aggressively break from 60mph down to 30mph as it approaches following distance of the nearest car. I also find it can get really weird in stop&go traffic, not easing into speed, down to a stop very well as if it has only GO or STOP.

Oh wow. This happens often with a car-mounted GPS (or on a phone) and it's pretty annoying. Sometimes the GPS instructs you to do a U-turn at the next available fork in the road, and it takes a moment to understand what's going on.
But in a self-driving car it's terrifying! And absurd.
