The result for me has been pretty predictable, I'm getting a kind of corrective feedback so I drive in a way that prevents that feedback. The practical result is that imo I'm a better driver, I'm more aware of my lapses in attention, my tendency to overcorrect to the right, and so on.

I'm yet to experience a downside, this isn't like using "Autopilot" or some other situation where a machine is taking over for me. I don't see why our skills or caution would be lessened by exposure to realtime feedback.
