Im not saying you don't have to be careful (hell i've hydroplaned while driving an ambulance with a patient in the back, wanna talk about nerve-wracking, 75 MPH on the interstate in a top heavy box with a trauma patient in the back and you start hydroplaning) i'm merely saying that due care, and WOT/VTEC are not always mutually exclusive in the rain. I mean honestly, with your logic you should never use WOT/VTEC on the street ever, even in the dry. Because yes, regardless of condition, partial throttle is ALWAYS safer therefore ALWAYS the wiser option. That said A lot of it comes down to what the driver is capable of recovering from.
