I HATE hot weather, but my car loves it! We hit a little bit of a heat wave yesterday and I believe I hit a new record for work-and-back. 7.1 miles total, 97.2 MPG. I can often get 100+ on the way to work, with being plugged in prior for good warmth and a fresh charge on the 12v system, but on the way back, I'm at the mercy of ambient temps, not to mention elevation gains.
So I'm hoping for a fruitful summer. If I have to put up with 90+ degrees all season long, I better get 90+MPG, too!
