EV pickups are going to happen, big time. Think of all the states that will mandate their entire work truck fleet be electric the day they're available. They may save the Lightning name for the street rod, but maybe not. We'll see. It's clever enough that they may decide that they'll use it across the line and call the drag racer the Lightning R or something.
I think we are long way from that happening for pickup trucks. Delivery vehicles would be the first to head this way I think. Because they have a more predictable/manageable use, they tend to be larger corporations that could invest in an EV fleet, and they are more visible to consumers who might care about that. Even then, we have lots of delivery drivers using their personal vehicle, and it'll be hard to mandate that all Grubhub (or whatever) drivers use EVs.
I would think work trucks are used even more frequently as personal vehicles. That seems to be the case, particularly for small or self-owned businesses. Just look at lawn services, are you going to dictate that illegal aliens need to trade in their 90's pickup for a new Lightning? And of course, if you need to have over a 300 mile range for your work use, you can't dependably rely on EVs.
I think we are heading in the EV direction. There is no doubt about that. However, I have my doubts that we'll even reach 50% EVs on the road. Too many yet be dealt with issues with battery production and disposal that could slow or end progress, and too many situations where ICE looks like it will always be superior.
