It doesn’t help that US diverging diamonds seem to insist on having pedestrians walk through the median.
But honestly all interchanges are varying degrees of horrible and if you want your city to be bearable to navigate as a pedestrian/cyclist you just really don’t want to do urban highways, or roads above a certain size in general.
You could say that about any kind of autocomplete. Why would people install snippet plugins into their vim/emacs? Sure you can just type everything by hand but it’s just more convenient.
Personally I find these kinds of inline AI suggestions make a more convincing use case than trying to prompt engineer a Chat based LLM and diverting your attention to phrasing specifics instead of the actual problem space.
