We can boil it down to this: Some people think that gasoline will go away, others don't. Both positions are just opinions. EVs work great for some people, some still need ICE. As a corollary, a number of people--not everybody--who think they need ICE actually would do better with an EV. (There is considerable ignorance still when it comes to EV's.) Nevertheless, for some jobs you still need ICE. For short distances, a Tesla X tows just fine within it's limitations. For long tow distance, an ICE vehicle is still the clear winner. That may change in the future. Choice is good. Choose which vehicle suits you.
All of that said, politics could change the whole equation. There is a large faction in this country who want to take your choices away. They are likely to have the ear of those in power in Washington very soon. Please bear in mind that most Tesla owners--while fanatically enthusiastic about their cars--are of the mind set that you should have a choice about what you drive until market forces limit that choice. Teslas are about practicality mixed with serious fun. That doesn't draw the kind of people who hate your trucks. In fact, every Tesla owner I know--a lot--has a truck or full size SUV in their garage as well. I'm getting rid of my two ICE daily drivers,and replacing them with two Teslas. I also have a restored '92 Blazer with a six speed 6L80E trans and a 450 horsepower L94--dynoed--that I hope to keep until the day I die. We're all on the same side here, and there are a lot of people who don't like that. From the networks who stand to lose $18 billion annually in ad revenue, to the folks who want to get rid of ICE cars and boats tomorrow, to the politicians who will promise anything and do anything to get elected. A battle is coming, make no mistake. Try and not force anyone to the other side.
ICE is not a derogatory term. Neither is EV. ICE just means" Internal Combustion engine." It is merely a convenient term to differentiate two different types of vehicles. We never needed it before, because EVs were so rare. I spent a lot of time, muscle, money and blood restoring my ICE '92 Blazer, and I love that truck. "I love my truck, I like my girlfriend". Best line in a song EVER. Well, that and "Everyone knows the world is full of stupid people". Anyways, I wouldn't refer to my Blazer as an ICE vehicle if I thought "ICE" was a derogatory term.
Here are some facts. Teslas can be had for $40K. Cost of operation is a fraction that of most vehicles. Teslas have far less to go wrong than other vehicles. Teslas are meant to last a million miles. Whether or not they achieve that is still undecided, but at least that's the intent. Most other vehicles these days are designed to be junk by 200K. For instance, most automatic Nissan's have a transmission heater that is always in operation. Not a cooler, a heater. This heater is great for initial warm up, but should be deactivated as soon as the proper temp is achieved. Nope, it just keeps heating the trans, so that the trans is ALWAYS overheated, even under light load on a cold day. Given that high temp is the #1 cause of tranny failure, it's clear that this design is intended to cause transmission failure somewhere between 100K and 150K. Obviously, it's not possible for a Tesla to suffer a transmission failure. (Teslas have no transmission, or center differential either.)
More facts. If the area you live has cheap gas and expensive electricity, EVs will not have as big an advantage. If you have cheap electricity and expensive gas, an EV rapidly becomes more financially attractive. If charging stations are not available in the area you make trips to, EV's will not be as convenient as they are in other areas. Currently, Teslas are far more convenient to take on road trips than other vehicles as the charge time at Tesla superchargers is a fraction of the time it takes to charge non-Tesla EVs. Teslas can charge at any charging station or anywhere they can access an electrical outlet. If the outlet is 220V, a full charge can be had in as few as six hours. (15 minutes at a level 3 supercharger.) Many EVs have such limited range that they are useless for anything other than going to & from work. Teslas do not suffer from this limitation, with 250 miles currently being the lowest range option. For 99% of the people, in day to day driving, you will never need to charge a Tesla anywhere but at home overnight. Those people will spend far less time charging their vehicles in the course of a year than they used to do fueling up a fossil fuel powered vehicle--even with the occasional road trip thrown in. You don't need a Tesla charger to charge your vehicle. Plugging in to a 220v 40 amp circuit will give you 32 miles of range per hour. Installing a $500 Tesla charger--plus the cost of installation--will give you 44 miles of range per hour. 110v is only going to give you about 4 miles per hour.
I personally think gasoline will go away within my lifetime. Probably much sooner than anyone now believes, but that is just my opinion. I believe market forces will drive this. Politics may drive it much sooner, though I would fight that tooth and nail.
Back to towing: I've got a Tesla Y on pre-order. I'm hoping it will be rated to tow 5000 lbs like the X is. (Rating is unknown yet.) I'd still do all of my towing with my Blazer, but it would be nice to have the option to use the Y if the Blazer was out of commission. It's less than 10 miles to my marina, so range is not an issue.
