I think I'm passing a milestone. Im on vacation and I took a long drive diapered. During the 5 hour trip I only took 2 stops 1 for gas and one to let my dog pee. It took a whole lot of effort but I managed to wet numerous times. What worked for me was to sit how i do gaming. I got a nice gaming seat very similar to my car seat. It honestly took a long time to figure out how to wet while driving. I sit as i do gaming at least for a few minutes. It was just that easy ish!

Edit: for those that asked how was cruise control and sitting on my right foot, no not cross legged and i dont actually like that position to drive like at all but effective. Its more of i dont wanna have to stop at a sketchy stop
