Clothes dry faster when you attach the posts to the front and back bumper of the car and hang the clothes before going out to do errands. Doesn't take up space on the balcony. It is efficient to time the laundry with grocery runs since you will be unloading the car anyway. Two armloads of groceries can be too heavy but one of groceries and one of whites is alright. I use my truck since it has a lumber rack.I can hang multiple lines. Sometimes I don't have time to take the clothes off so I park across the street from my house. I got too much stucco on my truck during one job. It was easier just to stucco the whole thing than clean it. I think it is an original idea. HOA doesent like the color though. It has nice texture.
I prefer sticking my clothes in the engine component after my spirited ride to and from the grocery store. Things dry in a few minutes, especially with a turbocharged car. There's plenty of heat leftover even after grilling my lunch.
It's pretty simple..Stick your favorite salmon, corn, potatos wrapped in nice aluminum foil. Secure the wrapped food next to your turbocharger or engine block, ensuring it does not slip into your timing belts, drivetrain, etc. Go out for a nice spirited ride to the grocery. Come back, lunch is done, and throw your nice pj's on the engine block.
