On this current 200 mile trip the last half of it where I normally can get in the 42 mpg range I have been stuck at 38 mpg. It's been raining steady and there is a thin layer of water on the road. On the slower city streets I can't drive under E mode much as the rain on the road really offers a lot of resistance to the tires.

I've even tried some of those "crazy" hypermiler" tips to no avail
