Vomit bags, urinals and portable toilets are not something people usually like to talk about, however when driving for Lyft, Uber or other ride share, taxi or transportation services, you never know where you'll end up. Sometimes you may find yourself out in the middle of nowhere or even in a busy city without access to restroom facilities. How many times have you seen the signs "Restrooms for customers only?" When nature calls, you have to answer. Aside from peeing in your pants, these urinals and portable toilets may come in handy.
Vomit bags are great to have on hand should your passenger get sick. Better they vom inside a bag than in your car.
Better to have and not need, than need and not have.
