However, now that I have the adaptive cruise control, I get anxious that I might get into an accident when I think it's enabled while it isn't. Another concern is that it won't be able to apply braking hard enough when a collision is imminent - in such situation it flashes a red warning on the display and sounds an alarm prompting me to brake, but because I haven't been actively adjusting speed with my foot, it might increase my reaction time.

So perhaps having more of those "half way there" self driving features could lead to more of such anxiety, I'm not sure. And I don't know who I would trust more, a car manufacturer, or someone like Comma AI, with my safety. Leaning towards car manufacturers to be honest.
