Please explain why you think they won't be needed.
I am very interested in this point of view.
Similarly to
@LastDayScout, I'm only speaking from my own experiences:
We've driven hybrids since the first generation of Prius (2002). We loved them, but always wanted an all-electric. At the time they came out, we couldn't even dream of affording a brand-T (and I thought the crazy train picked up the dude way back in the early 2000s). We have always gone camping and done road trips, and a hybrid was fantastic for that--compared with regular ICEs. We live 150 miles one-way from my wife's office that she has to travel to about once a month, so when the Leaf came out, it wasn't an option. And we couldn't afford it anyway.
When we could finally afford an electric vehicle we knew we didn't want a third vehicle, so we looked and looked for a road-trip worthy electric vehicle. For us a road trip is long enough that returning on the same day is either a stretch or just not possible--that's at least 450 miles or so. Our usual road trip is from northern Arizona to Pasadena, CA--I have family in the area and I have a work meeting there at least a few times a year. We needed to be able to bridge the 160 mile gap from the Flagstaff, AZ area to Kingman, AZ, which is where the only fast charger was when we were looking for charging. Knowing that our efficiency would be lower on the freeway, and knowing that we would unlikely charge to 100% on the way home, we needed something that could leave us with margin when driving those 160 miles, so we decided that the vehicle had to have a realistic range of at least 180 miles when starting at 80%. That's a 225 miles range on a full battery. Taking into account some range anxiety, we decided a 300 mile EPA range was what we wanted.
We also wanted an AWD because of the snow and ice we get here in the winter.
We got the Mustang Mach-E California Route 1 AWD trim with the extended range battery because it had 312 miles range according to the EPA.
We didn't need to worry.
We usually skip the Kingman stop in favor of the Needles stop (220 miles). And we have margin to make it to Najah's Desert Oasis (255 miles), but that's four hours away, which is too long to sit in a car.
We've found that 2 to 3 hours is our maximum driving time and it's not the vehicle that limits us, it's ourselves. We get tired, we get cranky, we need to go to the restroom. We need to eat. We need to walk around.
We took a road trip to Arkansas for the eclipse this past spring and decided to take the Tacoma because the Mustang isn't a great camping vehicle. We were cramped, miserable, and hated stopping at gas stations, especially the ones that were crowded because of the eclipse--most of the charging stations we saw were empty while the gas stations were full. We brought a 5-gallon jerry can because we were going deep into the Ozarks and weren't sure we would have the range to make it back out--that stupid can of gas is still sitting somewhere unused. We started looking for replacement vehicles on the trip home. The R1T and Lightning were the only options and both were great options. The R1T is still out of our price range, and we got a great deal on the Lightning.
Towing was a consideration when we got the Lightning. When towing with the Tacoma, we usually got around 8 miles/gallon and that was at 55-60 mph--we already had to stop on the way to Kingman (160 miles away) because of the poor range. We were quite familiar with range anxiety while towing, but it's now a thing of the past because we have an electric vehicle.
The last tow trip we took with the Tacoma, we encountered two gas stations in a row that were over-full with angry, impatient holiday travelers and with inoperable pumps or empty tanks. We arrived at the third gas station on fumes after having driven 20 miles at 40 mph on the interstate.
With the Lightning's 320 mile range EPA estimate (which I can regularly get while on the interstate). From experience, I know I can get >180 miles while towing a trailer on the interstate. That's better than I was getting in the Tacoma or its bigger brother the Tundra while towing. An EV with 350 miles range is a fantastic option and depending on the context when it comes out, the Tera may replace our Lightning. But we'll see.
With an all-electric (no Harvester and no other hybrid):
I never have to go to a gas station (saves me hours and hours a year).
I know I can get the range my eyes, back, and bladder are comfortable with, even while towing.
I know I only need to do EV maintenance rather than both EV and ICE maintenance.
I know most of my driving is local or road trips without towing.
I know if I really need a bigger truck to tow something that I can't tow with the Lightning I can rent something for the few days I need it.
I know it's much, much cheaper for me to own the Lightning than to own a similarly-capable ICE truck or hybrid.
