It could be the meds.

I have a friend who started running red lights after she went on a new med.

She'd sail right through them without even noticing that she'd done it. although she'd always been a super careful driver.

After she'd done it twice when I was in the car with her, I pointed it out.

She was alarmed, of course. She figured out that the med was making her space out without realizing it, so she stopped taking it in the morning and started taking it before bed.
