I used a Comma 3 (somewhat close to FSD, just simpler) and I found that it allows to you look forward in time more then you normally would. Normally you might be looking at the first 50ft for issues, now I find I'm able to expand out to 200ft and look around more for traffic.

Not having that much situational awareness sounds super dangerous. 50 ft is way too little for safe driving.

  Every day I drive, I see dozens of incidents where I think someone should be ticketed for reckless driving: tailgating, excessive speed, unexpected lane changes, etc They never, ever are. We do not enforce good driving except after people die (or even then, vehicular homicide has low sentences).

  It's not that I say 50ft is the only zone, but its my main focus, that and traffic around me (Mind you, this is all highway) With the Comma, it moves out a good bit, Allowing me to process more of the future traffic going on and the more edge cases that might come up at highway speeds. Also its vision and radar based so it keeps me 250ft+ from the car in front of me and keeps speed, it won't ever change lanes. This is why its more of a LKAS with better settings. Of course there are cases the system doesn't work at all and is not well suited for surface roads very well. Its behavior is very predictable and easy to feel when its seeing something I'm not. (Slowing down to match speed 1:1 with the car in front of me when they let off the gas is a common example)

    50 ft is just three car lengths. That's a really short distance while driving. If something happens suddenly in that range, you might not be able to brake in time even if you were driving at just 20 mph. You might actually mean a longer distance?

    50 ft is 15 meters and change, at regular car speeds that is much shorter than your reaction speed. It's essentially an accident waiting to happen. At highway speeds you should be looking about 200 ft ahead of you for safe driving. See the 'two second rule', and that's for clear skies, daylight: https://www.researchgate.net/figure/Safe-driving-distance-2-Second-rule_fig1_319851766 https://www.researchgate.net/figure/Safe-driving-distance-2-...

If you can't keep your visual scan out further without relying on a driver assistance system then you're incompetent and shouldn't be allowed behind the wheel in the first place.
