I have my full detail tote strapped down in my trunk, along with about 10 fresh MF towels. I also carry one in my center console for wiping finger prints off the z1, dust off the dash, or the occasional foggy window.
I have everything I need if I spontaneously decide I want to wash my car wherever I go (yeah, I have a bucket too) and do a full wax job, tire shine, interior detail while I'm at it. O_o; The only thing I'm missing is a vacuum. Well now I know what to ask for Christmas. ^_^v
I guess I'm just a weird detailing guy.
