Given that just about any EV model has an extended waiting period, you will need to put in an order and get in line. I've thought of the Ford EF-150 due to the ability to power the house during an outage. But, that "ability" requires a minimum of 320A service coming into the house and a dedicated 80A circuit to the outlet. As most houses currently do not have 320+A service into the house, nor the 80A circuit to the outlet, that would mean even more costs.
Can you provide a source for this? Why on Earth would your service size have anything to do with V2H? By definition, if the vehicle is providing power, your house must be isolated from the grid so your service drop is not in the picture. This does not make any sense. Maybe they are using service size as a shorthand to make sure your panel capacity is high enough to distribute the power?
The problem with any other automaker including VW is their battery tech and battery management system is not as sophisticated as Teslas. I have zero expectation that other brands will be able to maintain 80% original range a decade and hundreds of thousands of miles into the life of the pack.
I believe the opposite is true. No other manufacturer uses as much of their pack's usable capacity as Tesla. That is how Tesla gets such good range numbers. They let you really charge to 100% and really run it down to 0%. Other manufacturers hide more of the top and bottom than Tesla. These shallower cycles will mean better battery longevity over time, not less.
Further, I don't believe anyone else has battery manufacturing in-house so they must go with off the shelf chemistries and configurations from LG, CATL, SK, etc. Those manufacturers tend to be conservative with their specs as they don't want the liability of not meeting the specs down the line.
For the OP, I can say that after my recent experience ordering my MX Plaid, Tesla is no longer at the top of my list. The powertrain is outstanding - no question. But the UI has gone from bad to worse. Where the F is the button for the glovebox? It either takes multiple button presses on a screen or I guess you can disrupt everyone in the car by using a voice command. These kinds of decisions penetrate every aspect of the car. The yoke is an absolute joke. Customer Service during the process was nonexistent. Phantom Braking makes Cruise Control useless. And on and on and on.
While waiting for my MX I leased a Volvo XC40 Recharge. They have a ways to go to make the car more efficient (Wh/mi was quite high) but when it comes to driving and how I interface with the car, it was miles ahead of any Tesla. Further, none of their OTA updates broke anything that previously worked. Tesla has done this numerous times. Volvo also sent me an email before the OTA update came out with a link to the Release Notes that listed what was new, what was fixed, etc.
I will definitely be looking at other cars when it's time for a new one. I currently like the Lotus Eletra and the EQS SUV. As a former Corvette driver (C6), an electric Corvette sounds interesting as well.
The good news is that the other manufacturers are finally waking up and delivering compelling products, not just compliance vehicles. As more and more EVs hit the road, charging will get better as there will be an incentive to provide charging to paying customers.
I do still love Tesla and I hope that people voting with their wallets will force Tesla to fix these things.
