Zippy.... Not much information on your profile, but since you say that you live in the Tundra, a tank heater and or oil heater might help. That would permit you to get into the EV modes in less time. (It would also provide instant cabin comfort on those "tundra" mornings <grins>.)
Is your car garaged? Only 4 miles is not much time to actually get to the EV modes after an allowance for warmup. On very cold mornings you might actually never get to stage 3 operation. (If you don't know what that is look
HERE.)
If you have a choice of routes, chose a route with the stops at the end instead of stops at the begining. Sitting with the ICE running for warmup hurts FE.
One other thing, if you have any hills to climb on your way to work, can you select a route in each direction that climbs them early in your commute, during your warmup? That would get you to EV quicker and permit a longer time for electric drive.
