No, but I've been a passenger on ketamine with a guy driving on ketamine. He did just fine. It was pretty fun, actually. It was my first (and only so far) K-hole. Driving on acid, however, was pretty easy for me. I just made sure to concentrate on the road. I was never peaking while driving, and this was the time period where I was eating L, mushrooms, ecstasy and/or smoking DMT 2-3 times per week, which lasted for about 6 months. My friend once drove on an eighth of some ridiculous mushrooms. They made me trip harder than 7 dry grams of homegrown cubensis. He just stared at the road and told me to help him with red lights. He wouldn't talk and barely blinked. We made it fine, though. We took as many back roads as possible and never went over 25 MPH.
