"Roundabouts are] particularly challenging, where many drivers don't know the proper rules in the first place."
Only in the US. Elsewhere drivers have figured this out.
PS. Practicing star hopping when using standard charts without EQ mount, is kind of complicated too if your next star is not in the same field of view. Or you don't know which direction is which because your chart is completely out of whack.
Over twenty years in the hobby here and I can't say I've found this to be true for me. I can star hop just fine with a Dob and a star chart. Actually, most of the time I don't even need to star hop through the eyepiece. I just do it naked eye with a Telrad.
