ROFL I started to have that thought when I finished writing all that. It all depends on where you're driving. On 17.17.4, I did a 10 hour drive from Chattanooga to DC suburbs, and had to take over maybe 4 or 5 times for a few seconds (other than to exit for charging). It did very well! That 10 hour drive was much less draining because of AP. But try to go around the DC beltway for 10 minutes with HW2 AP and you've got a death wish. 10 minutes feels like 10 hours of hell trying not to crash and burn. It's basically unusable except for brief stretches or at slow speeds.
