Hello; The massive balls on the drivers helps with the balancing and maintaining the centre of gravity of the buses/trucks. This video makes me really appreciate infrastructure. A few years ago we had a flood in our area that cut us off from the primary larger towns where we go to shop for about a month. It was a weird experience not to be able to just hop in the car and go get what we needed. Got to admire the drivers who take this in their stride time and again. I mean, I get stressed pulling out onto a busy main road! And while we're at it, kudos to the build quality of vehicles that were designed to take their human cargo in smooth-tarmaced, shiny, swish-logo'd luxury and end up being thrashed like Toyota Land Cruisers! This video shows just how underdeveloped many regions still are, which regarding the time being 2022 is shocking. Those drivers got some massive skill though.
