That’s not how I would put it. I don’t feel unsafe with it. It doesn’t feel like a new driver at all, I trust it to do its job. I haven’t used FSD but from what I’ve heard it sounds less trustworthy to me (mostly because it tries to do more in more situations, BC is very tightly controlled).
But its job is to stay in the lane and keep a good speed even in traffic.
When using BC your job just like less advanced lane centering + cruise control: maintain situational awareness for what’s comping up + what other cars are doing. Additionally I keep my hands on the wheel anyway to take over when needed even though BC is hands free.
I do find it a benefit. But it’s “just” a lane keep + radar CC system that’s a bit more advanced. Just like every single other system on the market you can’t take your eyes off the road. Ford enforces it. If it was still active they couldn’t have been looking away for too long.
