No, the likelihood of incident is vastly lower in the air, but the required reaction time is not necessarily different and could easily be a lot lower, particularly if you are flying IFR. That's the whole point, much like in a car, a pilot must have eyes outside the cockpit.

Again, I'm not arguing that Tesla is right here about advertising, just that the two technologies are very similar in nature. The other big difference is the fact that pilots have to go through training and are tested on their understanding of the specific technology they control. Drivers, never have to be certified or trained on any specific vehicle.

If a pilot treats autopilot in a plane the way some people treat it in a Tesla, there would be a lot more fatalities in air travel, particularly in smaller aircraft with older technology.

That's the point, there is a vast difference in the publics perception of what autopilots do in aircraft versus what they actually do.
