Given the choices that were made, I don't think it can do the job it's marketed as doing, and I don't think I could safely and reliably supervise a car that's expected to partially drive itself.

I much prefer to drive a vehicle where I'm clearly responsible, but the (on by default) assistance features might help me out from time to time if I screw up. A computer doesn't get bored of checking if there's a slowing vehicle or (if it checks for them) stationary object in the path; but I'm pretty sure I wouldn't stay alert enough to jump in. OTOH, I also don't like using cruise control either, but that's not because I want to stay alert, but because without radar cruise control it's too much work to use, and I don't like the following distance options for the radar cruise control I have access to.
