I feel like you'd have to drink a lot of coffee...

  In a small segment of the population, a few cups of coffee may be enough to cause mild forms of the mentioned symptoms. But this is more of a genetic anomaly / over-sensitivity. In an "average" adult, it would require a lot of caffeine to trigger these symptoms -- dozens of cups over a very short period of time. Caffeine pills or powder would be a far more likely explanation. And yeah, driving after popping a significant number of caffeine pills is probably as dangerous as driving after ingesting a small dose of cocaine. TBF if the caffeine concentrations were such that this were a likely explanation, I bet we'd be hearing about it.

    When my tolerance is low it doesn't take much to make me twitchy and impair my thinking.

      > twitchy and impair my thinking I'm not sure how dangerous those symptoms are in the context of driving. Someone should do a study. I was referring to these symptoms, which are unarguably dangerous in the context of driving: "tweaking", paranoia, mania, even psychosis.

  At one point, I got a large coffee, about 20oz, from a shop in San Marcos, TX. After finishing it over 15 or 20 minutes, I found myself with a full on stimulant overdose: dizziness, sweating, confusion, irritability, shaking... It took me a couple of hours before I would have felt safe driving. I am a caffeine addict, at about a pot per day at the time of this story.

  I'd argue you probably couldn't consume the necessary volume of coffee to get that kind of dosage. You'd probably need to take caffeine pills.
