Four honks in twenty miles! And that is only counting the geese wanting to overtake, not the honks from annoyed motorists in opposing lanes.
On the route I needed to traverse today, I could have predicted two of them, because Texans think a cyclist ought not be in the travel lane if there is an improved shoulder. But the other two were extremely rare.
In chronological order:
First Goose; This fella had the bad luck to come up to me at place where he could not pass me safely in the 55 MPH signed speed limit road, shown here.
He stayed behind me and honked as if I were the one without the right of way. I guess he failed to remember the rule when he first got his driver's license that the faster traffic has a duty to overtake slower traffic in a safe manner in with due care. Perhaps he needs a refresher course!
Rather than passing me on the blind hill like many of his neighbors do, he waited until we got over the rise to pass me. He came up beside me on my left in the other lane, and slowed to set me straight about how to ride a bicycle. He had to occupy the opposing lane to do this because I was maintaining my position in the left tire track. If anyone cares, he was driving a recent model heavy duty red pick-up truck. Oh, and I spat in his direction as he began to overtake me. SOP. 
Middle aged red pickup driver: "You need to stay out of the road, someone’s going to run you over!" These words were not said in a angry tone, just a raised voice to be heard over the truck’s noise.
Middle aged bicycle rider: "So you admit that you are such an incompetent driver that you would run into a bicycle in the middle of your lane?" Yes, I really did ask him that.
Middle aged red pickup driver, after a pause; "It’s really dangerous to ride like that!"
I then studiously ignored him until he continued on his way.
I very rarely get honked at (Or even shot, for that matter!) on these two lane roads. That alone was unusual. But this fella, after being annoyed that I was causing him a trivial delay, adds 40 seconds or so to his delay by pacing me!
On north Kaufman, traveling north, just after it is reduced from a four lane to a two lane, this goose honked multiple times. Then he passed me on the improved shoulder at this spot:
As he passed, I spat in his direction, SOP. As he re-entered the roadway, realizing that he had been insulted he slammed on his brakes, coming to a complete stop, and marking the road like this:
I avoided him and came to a stop beside him. This is the hardest position for a motorist to strike you with his car.
Rolling down the passenger window he communicated to me.
Angry automobile driver; "You can't ride in the middle of the road, you are in the way of cars!"
Calm and witty cyclist;  "You have a duty to pass slower traffic in a safe manner and with due care."
Angry automobile driver; "Your not supposed to be in the way of traffic!"
Calm and witty cyclist; "One of us here has operated in a legal manner, and the other one has not."
Angry automobile driver; "I haven't done anything wrong! Your the one breaking the law!
Calm and witty cyclist, as traffic begins to work their way around us on the shoulder; "You don't call a panic stop in the middle of the lane reckless driving?" I suppose it should be noted that his right front fender was crumpled as was his left rear fender. I suppose he could've used working anti-lock brakes. Just say'n.
This comment seems to get him worked up. The angry automobile driver then said, roughly translated; "I have a good mind to hurt you in a bad way and make sure you stay at the side of the road!"
The calm and witty cyclist said; "Four seventy-five ex eitch are."
Confused automobile driver; "What?"
Calm and witty cyclist; " Your license plate number, four seventy-five ex aitch are."
As he speeds off, I re-enter the traveled portion of the roadway and continue on my way.
After being so upset by my having delaying his trip that he broke the law by passing me on the shoulder,  he recklessly stops in the lane to spend over a minute "speaking" to me.
Third goose; Now traveling south on north Kaufman, I ride into a construction zone where Kaufman's four lanes have been reduced to two. Another motorist honks like in a futile attempt to improve the situation. As the road expands to normal lanes I do not spit, being unsure of which driver following me had poor impulse control. I pull up to a stop behind them at the next light.
Fourth goose; As I nearly complete the final part of my ride, on the 55 MPH signed speed limit two lane that connects to my driveway, while safely overtaking me in the oncoming lane, the elderly man honks as he goes by. Did he know about my SOP?
It is uncommon that anyone ever honks at me on a two lane without a shoulder. Both honking and passing on the right are expected on a two lane with a shoulder. Four same direction honks and two opposite direction honks in twenty miles is considerably odd.
Two of them were sufficiently outraged by my lawful behavior to interrupt their trip to publicly chastise me. They were not satisfied with simply being ignorant of the traffic laws. In their certitude, they were determined to make sure everyone was aware of their ignorance!
 SOP: Standard Operating Procedure
 Hey it's my story, and I can tell it any way I like.
 He illegally passed on the right: Sec. 545.053.(a) An operator passing another vehicle shall pass to the left of the other vehicle at a safe distance.
He illegally traveled on the shoulder:
Sec. 545.057.(b) An operator may not pass to the right by leaving the main traveled portion of a roadway except as provided by Section 545.058.
Sec. 545.058.(a) An operator may drive on an improved shoulder to the right of the main traveled portion of a roadway if that operation is necessary and may be done safely, but only:
(1) to stop, stand, or park;
(2) to accelerate before entering the main traveled lane of traffic;
(3) to decelerate before making a right turn;
(4) to pass another vehicle that is slowing or stopped on the main traveled portion of the highway, disabled, or preparing to make a left turn;
(5) to allow another vehicle traveling faster to pass;
(6) as permitted or required by an official traffic-control device; or
(7) to avoid a collision.
He operated his vehicle in a reckless manner without due care: Sec. 545.401.(a) A person commits an offense if the person drives a vehicle in wilful [sic] or wanton disregard for the safety of persons or property.
Curiously, this is the statute he accused me of violating. To whom does it most accurately apply to? Sec. 545.363. (a) An operator may not drive so slowly as to impede the normal and reasonable movement of traffic, except when reduced speed is necessary for safe operation or in compliance with law.
