Walking bulldozer (human AI)

A walking bulldozer is classically a human pedestrian who will attempt to 'intercept' you by walking towards you and ploughing into you like a walking bulldozer. They may also operate on linear paths but this generally applies to people who bulldoze you when you're safely out of the way (as if going out of their way to do so).

Walking bulldozers are classically found in crowded shopping environments especially where trolleys are involved.

Reasoning
The reason walking bulldozers exist isn't entirely clear. On first glance it would simply appear as if the individuals are merely brash, but on closer examination, they appear to go out of their way to drive into people who aren't even in their way. It might be contrued as a personal issue (ramming people out of spite or some personal issue) however walking bulldozers tend to exhibit 'heatseeking' behaviour and terrible depth-perception and/or visual spatial capabilities.
