Tom Tom sat navs are clever, they don't give speed camera warnings which is illegal but they give you a danger warning triangle instead. Strangely at same place as speed camera sites! Have been flashed many times in France when absent minded and so have fellow riders and they don't send them through for bikes. You don't need helmet stickers regardless of what has been said on this site. Warning triangle high viz and breathalysers are a must. But in a group we just carry one set between us for space.
