How expensive does electricity have to become to negate any savings? In parts of Hawaii it is well over 40c kWh and San Francisco or San Diego are right there. They do offer some EV reduced rates but for how long?

Watching some of the pickup EV videos linked above, some of them were towing at about 1.2 miles per kWh. And one had a Ford F150 that was getting about 10 mpg for the same task.
So, 100 miles at 1.2 miles / kWh = 83 kWh
100 miles at 10 mpg = 10 gallons.
If your power is 20¢ / kWh, one gets $16.66 for the trip. If your power is 40c / kWh, and one gets $33.33
If your gas is $4 a gallon, it is $40. But, in Southern California, bet it is closer to $5 or $6, so $50 or $60.
So, the higher the electricity, the less benefit.
On the other hand, if you get an Aptera (assuming it makes it to the market), and park it in the sunlight, the power consumption will be almost zero, or may, in fact, be ZERO. Compare it to a gas powered moped.
Overnight charging was mentioned earlier. Solar is zero at night. But, hydroelectric, wind, and nuclear can continue throughout the night. Some power sources may choose to reduce their output during low load periods, but most will not wish to shut down to zero, or can not shut down at night.
Thus overnight wholesale energy may be cheaper than daytime energy. And California is already rewarding people who charge at night.
I do wonder if our grid is designed to support the extra load.
I've been charging my Transit Connect on about 10A, 110V. Slow, but I can not detect it on my electric bill beyond other power consumption. However, if one starts sucking down 50A, 220V all night long, or even more, that will make an impact.
