Say that you like the parks and forests in places like Montana, Arkansas, Utah, New Mexico, etc. You're going to do a lot of driving along state highways with a lot of nice things packed away, and maybe a small water/dirt vehicle.
Most of those state highways have small towns every 20-80 miles where the speed limits briefly drop in increments of 10mph down to 30-40mph. In these towns, if you have out-of-state plates, you will regularly be pulled over for doing 5mph below the speed limit. You can expect a dog to sniff around your car if the patrol has one. You can feel the desire to just take everything that you own; it's palpable. I've gotten enough "warnings" to make a suit out of carbon-copy paper.
That's to say nothing of racial prejudices in many areas of the US, and you'll probably have to stop for CBP checkpoints in states like New Mexico, even in the middle of 80mph+ interstates.
It was a bad situation in 2018-2019, and I can't see it getting much better when restrictions start to lift in 2021. We badly need our courts to strongly re-assert the 4th Amendment.
