Again, highly dependent on your ability to charge. I'm not talking about just the Lightning, there are multiple different vehicles with different size batteries that you seem to be forgetting about. Yes, it can take many hours to charge the larger batteries, even on 240V, and depending on the amp rating. If you are only getting 60-70 miles out of your EV truck when loaded, waiting even 40 minutes would be too long for most people who actually need to get work done.There are all kinds of use cases where it fits, and as many more where it doesn't.
I know plenty of poeple in my area that do make constant short hops and make numerous short range tows and pretty much every small farm has at least a a 50 amp outlet somewhere so you can start every day "full".
Doesn't sound like you have any actual experience with BEV charging.
On trips you dont charge to full but closer to 80% and its fairly quick 1/2 hour 40 minutes or so.
It's not remotely "many hours" and not even close to half a day before it can be used again as you claim.
The lightning is far from the fastest charger, but it's way better than your claim.
This group has been watching it and I posted speeds in a different thread.
The other big problem beside range with long distance towing and Ev's is the lack of pull through architecture forcing trailer disconnect at most places even if it had the towing range - this issue makes it untenable more so than charging speeds.
Again, maybe it works where you are from. It doesn't work here and unless EVs develop a way to charge a battery in 5-10 minutes to a full charge without reducing the life of the batteries, its going to remain a non-starter for people who need to get real work done.
