Hello I have done that it depends on the kind of vehicle you have. If its a Minivan or suv its nice cause you have room to hop to the back, with a car or truck its much harder. It saves you time from having to get out locks the doors and run and to me it does kinda help with the anxiety you have to worry about
finding a place to go. I have been told though i cant seem to find it yet. There are people who will install a small bathroom in your minivan if you are disabled.
