See here but all three senteces, pls. We're a frequent operator in the north-east quadrant of Vienna, going to all of the capitals within 4 hrs radius. And I'd say there's no need or practical benefit to turn it on in the exact conditions you describe.
Caution before engaging in a heated argument somewhere: WET for tkof perf purpouses embraces up to 3 mm of water, only then it becomes water-contaminated. For practical E-AI purpouses, standing water they warn against comes much sooner than 3 mm - I'd say.
Look outside, use it when you need it or the book tells you so, and do not load other people's guns when they aim at you.
