This is why you should ALWAYS read the manual:
From both the pint and XR manuals:
Avoid streets and surfaces with water, sand, gravel,
dirt, leaves, and other debris. Wet weather impairs
traction, braking and visibility.
And then just a little bit later in both manuals:
Water damage is not covered under warranty
Right in the manuals -- and to me this says: Don't ride in wet conditions regardless of what you see in video's.
