Normally, after driving through a large puddle or water that splashes the brakes, you'd tap the brakes to dry them out before you relied on them to really stop. Even the Bolt's manual recommends this (pg 195). But it got me to thinking: would the instruction to "lightly apply the brake pedal" would actually trigger only regen braking? Or, does the Bolt apply the friction brakes "lightly" ever time the brake pedal is pressed, even if we think it's using 100% regen braking to slow us? If not, I don't see how to squeeze the water out, short of actual hard braking. Unless the Bolt periodically self-applies the brakes specifically for this purpose. I believe my old car did that, but I don't think I saw the Bolt manual mention this.
