A proper dual fuel generator hooked up to your home would be a better alternative to a vehicle anyway. V2h is limited by vehicles battery state of charge. These new propane /gas generators seem way more cost effective and more useful overall.
I use a higher charge setting when the weather forecast is bad. Wide spread wether outages don't happen without warning. Local outages always have crews available for a reasonably quick fix.

I typically wait a couple of hours before getting out the portable generator. But I would like to plug in a truck inverter after maybe 10 minutes

If anyone thinks Tesla has not carefully tested or actuated the benefits and requirements of a V2H or V2G implementation, then they are about as familiar with Tesla as Gordon Johnson, Craig Irwin, or Dan Nathan is. Tesla knows it's battery chemistry, charging systems and inverter technology better than anyone else from the sidelines.

I still maintain that for many owners, it would be a feature that incurs more costs while getting seldom used.

I'm not in line for a dual fuel generator. So I would have to buy something in addition to a truck, doesn't seem cost effective to me.

Why make a separate purchase if your truck can do it? Especially if you have solar.

With that massive battery, why has Elon decided not to provide us with bidirectional home charging? Unless just to force us to buy more PowerWalls? C’mon, Provide us this basic need that ALL EVs will eventually have. Its not going to be easy to add that after delivery.

Why are we assuming no bi-directional?

Really it’s actually pretty simple with that 240v outlet. You make a cable with 2 male ends.
There's a reason those are called "suicide cables"

I'm sure Tesla has studied V2* technically and financially and brand image-ly and and and. After all that study, they came up with the wrong answer. Their assumptions and needs and cost/benefit are not my needs and cost benefit.

I'll agree with you that most people won't have the technical know how to use V2* often or well, at first, until it's a commonly known and understood technology, like it should be. But if V2L saves one life because someone can get the power out of their battery safely, then it's worth it to me to have V2L onboard. Every vehicle.

If you're talking any possibility of a life critical situation, then one should've already had a means of backup (such as a generator or Powerwall) already interfaced and ready. It's not realistic to act like V2H is somehow required as a first option in that scenario. This is what a Powerwall is for, and it would be much more reliable to meet a need in that situation.

Putting V2H in every vehicle would be a waste and there's also limited and uncertain availability. If a power outage occurs in an area, the nearby superchargers are going to be out as well, so if a CT only has 30 percent or low SOC or hasn't recharged yet for example, then connecting it to the house is not going to provide much.

The 'life saving possibility' argument is uncertain with V2H, because one can never know what the SOC of a Cybertruck would be when a power outage happens to occur, so one can't say that critical power reserves would be available anytime needed.

Totally wiser to have a dedicated backup solution with a full charge awaiting, than to gamble on what might be the SOC of a Cybertruck when a power outage happens to occur.

Additional cost of bi direction charger ~$800
Additional cost of installing it... ?

Cost of a generac 7.4 kw generator ~1200 cost to install it probably similar to installing the bi directional charger....

With generator house is powered when you are away with CT.

Don't worry mom I will be home in 8 hrs.....
Generator wastes fuel idling on low loads. My neighbors with the big Generacs ran out of fuel during the storms this winter while I could coast on my 3kW of battery.

A small battery backup is sufficient for when the truck isn't there.
