I drove 20 or so minutes each way to my friend's horse far. Not one day did we miss seeing one or more dead dogs on the roads.
Too many dogs in shelters picked up from being lost; or hit by cars.
While my Rottweilers and first basenji were solid off leash, they only place they got to do it was at my friend's farm. And they weren't just turned out, I was out with them.
In the old days, almost all dogs ran loose. The norm... and if they died or were lost... well, get another one. Many died. I quit talking to people about it. They say "they want to be loose" and I say "so do toddlers and 3 to 5 yr olds... I still don't open the front door and send them on the world. " They get mad, I get mad, nothing accomplished.
We all take risks and avoid others. Unleashed is one of my "no" areas. And rawhide.
Absolutely dogs raised in a village in Africa are not the same as here. I think most dogs don't get enough exercise and mind stimulation. When you do that with an intelligent breed like basenjis, you're going to get unwanted behaviors.
You may want to read up on Dr Jo Thompson's work, as she also lived in Africa with these dogs. What wonderful experiences those of you who go to see where they came from.
