In the manga it literally looked like she tried to run over Keiichi, while I know she's the reason for the holocaust-esque deaths of Hinamizawa, and Rika, i'm still questioning if Keiichi "Exxagerated" anything in this scene since he did in fact have the syndrome during this time as well.

Spoiler for Possible spoilers?:

Well, Keiichi suffered from it in arc 1, so.. I'd say it's a safe bet he has it in arc 3, particularly since he seems to go to more insane assumptions ("they're all out to get me!") and decisions than I would think he normally would.
Not sure if Takano tried to run him over, though I also don't think he would've exaggerated anything she did or said in that scene. At that point in time, she's supposed to be 'dead', and Tomitake should be dead in her trunk or something.. so she's being generally suspicious in the first place.
