No need to be baffled, it was a simple case of typing quickly. MN isn't a professional context.
I've fixed it to ease your bafflement:
", when you’ve driven at an excessive speed past many cars that were waiting.”
Just so you're not worrying that I'm not aware of tense, or relative pronouns.
I do use colloquialisms, I'm very fond of them. Indeed I like to go further & very much like to pepper my English with my other language, which is Scots.
A favourite colloquialism is rips ma knittin'. For example, I may say that unnecessary pedantry rips ma knittin'.
Now, you also have a happy weekend, obvs.
