In what way is it useful? What value is being provided? In my experience it requires constant supervision and readiness to intervene at any moment. There are plenty of reports and photos of it running wheels into curbs with little time for the driver to react. Given that, while using it you do not regain any time or attention that you would have otherwise spent driving. That doesn't mean it isn't impressive. A car that can drive itself like a 15-year-old on their first outing with a fresh learner's permit that needs constant coaching from a parent or instructor is very impressive, just not useful. I will say that in clear conditions on long highway trips, basic Autopilot does have utility. It does allow you to divert some attention from keeping the car between the lines and matching the speed of the car in front, and use that attention to keep an eye on the large traffic picture, and arrive to your destination slightly less fatigued. Using FSD on city streets seems like the opposite of that to me, an increase in stress and workload that currently provides no practical utility.
