When John Denver wrote a song about our roads, he was taking artistic liberty to leave out the reality of the typical country road.
Many curves on the windy roads would be considered swerving. Thats why I found the game "Pole Position" easy as a 14 year old.

We get plenty of practice dodging critters by dodging Pot holes constantly. You guys are talking about whether to swerve or wreck. Sometimes you have to wack a mole with tires. Most of the time, well, you do what you can and complain about the high taxes and bad roads.

We don't have all that many roads where you don't have to swerve on a daily basis. I used to have to replace wheel bearings and other front end components every year after the parts warranty ran out . It's a necessity to drive something that has heavy duty ground control components, especially the front end.

Our country roads follow creeks. So, you practice missing potholes that might eat your car, without going into the other lane where there's usually a truck coming around the blind curve dodging his own string of holes.
On the right are some trees to stop you from plunging into the stream if you over compensate.

Animals are further down on the list of hazards, but definitely a major reason of our high insurance costs no doubt.
