I somewhat agree with what cossey said vlad…
There are some shots where if you tried to set it up so you can see the “4th wheel” would completely throw the picture off and it wouldnet look nearly as good.
Take a few of his shots for instance… you can see 3 wheels, if he tried to go for the 4th he would have to use a low angle and it owuld ruin the shot…
There are always exceptions to the rule
