Keep them in the car just in case. I've been stuck on the freeway for three hours because of the accident and I've never been caught in a car without an emergency bag. They are very well designed and all you have to do is put the cup down, hold it and urinate. The gel absorbs everything so you don't spill anything and just toss it in the bag. It's super comfortable and very well made. I've used others that actually spill and don't have a well-designed cup. They are perfect for the job and essential for any vehicle.
