Most of the pickup and SUV drivers I encounter are fine. That includes most of the construction workers I see along my rural routes where there are lots of housing developments.
The problem children are very familiar, guys like some of my own cousins, guys I knew from my former rural hometown. They're 20s-50s, perpetually angry with an outsized sense of entitlement that they're owed something, and undersized abilities and education in an economy that left them behind. They're hot and tired driving trucks without a/c held together by duct tape and empty beer cans and believe their suffering should be your suffering because misery loves company.
I've considered having a jersey printed up with "My other bike is a Smith & Wesson" and "This bicycle brakes for deer to get better aim". That would convey the correct message that I'm one of them. Or pretty close. I'm a redneck in recovery.
