First of all, it's a brand new car! There are several factors that affect the first few hundred miles.
1. Transportation and test drives. These are usually not conservative and will affect the lifetime MPGe until you get more miles on the car to make those few miles negligible.
2. New tires. Brand new tires are quite inefficient. After a few hundred miles the rolling resistance will be significantly improved.
3. New driver. If this is your first EV, you probably haven't become acquainted with what has big impacts on range, such as HVAC use, tire pressures, driving styles, etc. If you care about efficiency, which most EV drivers do, you'll soon learn and improve. Considering you're starting in the winter, you'll see the highest HVAC load and your tires may already need more air, for example.
4. Battery conditioning. The car runs the DC-DC converter at a higher voltage during the first 500(?) miles to be sure that the barely-used-but-calendar-aged 12V battery gets properly charged and conditioned. This is probably minor, but it is still a contributor.
5. Other stuff I probably don't know.
So don't fret. Drive the car for a few months and then start worrying about the lifetime MPGe. Meanwhile you can be trying to learn ways to improve item 3 above to get better trip mi/kWh averages!
For what it's worth if you're comparing the numbers above, my lifetime MPGe shows:
I've been able to achieve 120 miles on a single charge (~6.6 mi/kWh), so I CAN get good efficiency. However, I've done a fair bit of racing with my car and probably use the heater a LOT more than you California guys, which obviously makes a difference. I also do lots of city driving where I'm not very concerned about efficiency or range because I've got great access to chargers.
