Uh, my buddy pulls a giant horse trailer with his Lightning. You buy the tool for the job. Incline while towing? Range anxiety is getting 8mpg pulling a camper in a v8 Tundra.
The issues with electrics generally exist with ICE, as well. Again, just buy the tool for the job you have.
RE: Battery -- this is* a concern, but unless Trump just unwound it (haven't read all his EV changes), manufacturers have to do like 8 years, 100,000 miles on a battery. In that range, you'd also see engine failures that "total" the vehicle.
The key to this massive cost in battery replacement is for the market for secondary shops to increase. As more folks can manage the high voltage, prices will stabilize. It's not that the job is hard or the battery parts, themselves, that expensive vs engine rebuilds...it's labor. For a battery without issues, you'll see a loss in range, but not until well after 100,000mi....sorta like an old beat up engine loses HP and MPG over time. A well built battery should go for 200k, easy, without a crazy amount of degradation.
