Reposition the Pebble slightly if Magic Hitch cannot see the ball

Could be a camera angle thing. I've occasionally encountered situations in which Magic Hitch didn't initially want to engage. I've used the steering controls to reposition the trailer manually, adjusting a little left/right or front/back.

There seems to be a sweet spot where the camera sees the hitch ball. It's got a reasonable tolerance, but if you're a little too far off the zone in one direction or another, it doesn't know what to do. I think the safety protocol is pretty conservative (not a bad thing), and when it's not sure, it errs on the side of “do nothing.”
