Angled parking bays along a kerb

Angles, Parallel Lines and Translation

A car park serves hundreds of drivers and not one of them had to learn a second manoeuvre. The same turn of the wheel works in every bay. For that to hold, the bays cannot have been drawn one by one: each has to be the previous one, slid along the kerb. That single demand rules out almost everything the line-marking machine could have painted.
