I use to drive so slow sometimes, that i only have to downshift and i arrive at stop at 2-3 Km/h then i look my 2 sides and dead angle then i continue. i use my brake only if i have to. This is sometime embarrassing, because people in my rear doesn't see any brake light but I'm stoped ^^^. if i think the guy follow me too closely i put a little feet just to activate the lights then i continue.
EDIT : In winter, even slower
