Ford to electrify F-series

It's funny you should mention this, as I get this BS a lot from drivers invading our cycling forum, conveniently ignore the fact that most cyclists also have vehicles and pay taxes, and when we choose to bike, have almost no impact on the infrastructure.
eCar drivers may not buy gas, but they pay the government in other ways, like registration tax, and tax on the fuel that is used to run the generators at their local power plant. Interstate highways are not funded exclusively by gas/diesel tax, and the money that is collected is not evenly distributed back into the states for upkeep of said interstate roads.

Time to wean off of gas tax and implement a use tax. Of course everyone will scream about "big brother" knowing where they are/how much they drive but if you've got a cell phone that ship has sailed already. It would shore up the funding deficit that's gradually worsened as the gas tax hasn't been raised in decades and overall fuel economy has improved and be a fair way for users to actually pay for the infrastructure they use.

See, people throw this stuff around like it's nothing. You don't quite grasp the quantity of energy you're talking about.
The Tesla "Wall Connector" details can be found here:
https://www.tesla.com/support/home-c...wall-connector
For the smallest Tesla at the highest possible rate (220V @ 80A = 19.2KW) you get 44 miles of range per hour of charge. Let's assume an F150e requires twice the power. To get 300 miles range in one hour, you'd need to deliver 261.8KW (we won't worry with efficiency losses here). That's 1,190A at 220V. For one truck. An average restaurant has, what, 100 parking spaces? Assume they're all charging at dinner time... That's 26 *megawatts*. A fairly typical combined-cycle gas turbine power plant will output about 400MW. So you'd need an entire power plant to power just the vehicle charging capacity for 15 restaurants.
The scale problem exists everywhere. Figure an average home development of 1,000 homes. Each home has two EVs, and they're all charging at night. We'll use Tesla's numbers. That's a demand of 38.4 megawatts.
As of the 2000 Census, Dallas has 484,117 housing units. Just assume half of those, with 1 EV a piece. That's 4.6 GIGAwatts. The largest nuclear power plant (with 3 reactors) in the US generates 3.937GW. So you'll need to add a couple nuclear power plants for every major city out there, much less all the smaller places.
Let's use solar, right? Assuming a location with fairly high insolation values (0.5kWh/m^2/hour), with perpetual sun and no weather, and a never-before-built 50% efficient solar panel, you'd need 76.8 square meters of solar panel to charge every vehicle. Using our Dallas example above, that's 4,594 acres of solar panels. And again, we're assuming perpetual sun, perfect weather, panel efficiency beyond what anyone has developed, and no efficiency loss.
EVs are great, so long as only the elite drive them so they can thumb their noses at us lowly gasoline-burners.
