Good point, but "And all the advice above", which covered just-wetted streets.

In fact, the harder it rains, the better off you are traction-wise during the first 30 minutes or so of rain.
I live in Seattle where it rains on and off more or less all of the time ten months out of the year so it's rarely an issue for us but after a couple of weeks in July or August when it hasn't rained I wouldn't even consider riding in a light rain. I would literally take a bus or walk before I'd get anywhere near a bike under those conditions.
