I'be been having trouble keeping to the standard mileage the Tesla has been selling us. I don't think I have a lead foot and I've been getting only 70-80% of the estimated mileage. So at 90% charge, Tesla estimated mileage on my dash says 226 miles. I've only been getting 160-180 out of that (essentially 70-80 miles out of the 100 estimated miles) Am I the only one? I have a 90D and downgraded from 22" wheels to 20" wheels. It helped a little but not much.
