You're harming yourself doing this. First, sitting for long periods of time isn't good, and getting up and stretching every 2 hours is recommended. This applies to office work just as much as driving. Second, urination typically happens every 3-4 hours, and if you're not, then you're likely dehydrated or have something else going wrong.
If you really, really want to do this, well OK, but we shouldn't put the whole EV transition on hold just to let you do this.
