And heck, I could see specialty companies rent out showers and such to people who have been riding in their car to their destination - their own "red-eye" version but on wheels - so they can get cleaned up and dressed for the day when they get there. Hourly motels might not be "just for sex" anymore. Or a national chain of gyms - or whatever.
Just FYI, truck stops have this already, and have for decades. Usually they are free if you purchase 50 gallons of fuel or more, but they are also pretty cheap if you just need a shower. I used them when I was mostly broke and driving WAY too far for job interviews in the summer time in a car without a/c.
