For that matter, I don't see how it's likely that a tree branch could be

If you ride in the middle of the traffic lane, you're correct. If you
"stay to the right," whether on the shoulder or in a painted or
protected bike lane, the SUV is not going to be there (at least they're
not supposed to be there).

"Taking the lane" sounds good in theory, but realistically, most
cyclists stay to the right.

Do you not have buses? Most residential streets in London and even some of
the bigger cities will have large bus networks which use residential
streets as well that’s where the people are, And with London are double
deckers in most cases. Are places where the bus has to driver further out
but they are uncommon enough to require signs warning buses!

I can't speak to Santa Clara or London specifically, but most places the bus routes are on arterials while savvy cyclists are a block over on a less busy parallel street

 True, but tall vehicles like Amazon delivery vans, Ford Transits and similar vans, pickups towing trailers, garbage trucks etc. are on all streets at least occasionally. If there were such low branches over the roadway those vehicles would get damaged and/or the owners would complain to the city.
 On roads, the problem is imaginary. On every bike trail I've seen, the problem has been imaginary, other than one incident when a storm tipped over a tree.

It's not uncommon in this area for low branches to encroach on multi-use/recreational trails.

 And even then, I saw that hazard in plenty of time with my Busch & Mueller headlight with a properly cut off beam. Those who imagine zero light above the cutoff are also imagining things.
 Unlike Tom Kunich, Mr. Scharf knows how to post links to photos. If the problem were real and common, he'd have given evidence by now.
