Since temperature becomes more important now i noticed that car air conditioning is a bit to powerful. It cools the inside of a car down to -20°C to -30°C (!) however heating, on the other side, looks fine with around +30°C as far as i can tell.
The other thing I noticed is, that you need a lot of bath towels to dry yourself (like more than 14), which is kind of inefficient for a bath towel. Oh and you can't dry the bath towels in a dryer for faster re-use.
