My situation is that I work at home, so most of my driving is visiting friends, shopping, hospital, movies, etc. So usually not more than 25 or 30 miles, out and back. But a lot of that is on the freeway, and I have heard that it is better to use HV mode (rather than EV only) on the freeway. However, I read in another post that if your driving distance is within EV range, it is better to stay in EV mode the whole time, and use the HV mode only if your distance is going to exceed the EV range (and then use it on the freeway, with EV for the city driving portion). Can anyone give me their thoughts on this? I would like to stay in EV the whole time, even on the freeway. Will driving in EV on the freeway often/all the time have some other negative effects? Damage/wear out the motor, transmission, battery faster? Sorry for the newbie quesiton. BWT, my car is the 2018 Clarity Touring (just bought 2 days ago) in Northern California. Thanks!
