There is very little reason to be in a state where the advantage is the difference between a collision and not, is I think what they were referring to.

Adequate following distance, conservative driving, etc.

Not like that happens on freeways in any city, of course, but the point is - it shouldn’t matter, but should be nice to have.

Unfortunately, I’ve had numerous false triggers (highway construction barriers coming in rapidly from the side, while other traffic merged in), which made me disable mine. It’s almost caused several accidents in the last few years.
