O way it handles things on streets
Step-by-step explanation:
There is a needless ambiguity in this phrase that would just confuse the reader. it is not good prose when you can use just as many words and explain what the problem is but instead just use the word 'things' to describe them.
The sentence begs to understand what exactly it is that the car does not understand on the road or has a difficulty to follow but this is left unanswered in the text of the paragraph.
So this is where the author must re question their word choice for the passage.
