Yes, there are still a good number of free charging stations around, as well as (tesla specific) people who still have "free unlimited supercharging". YOU may be thinking "I will just do this once every couple of years", but there absolutely 100000% would be people who would try to power their home on free electricity on a constant basis by going to a free charging station, then driving back home to plug in.
Before you (or anyone else) says "people who can afford a tesla would never do that", all one needs to do is look at how many people who own teslas with free unlimited supercharging line up to "get the electricity they are entitled to", while NOT on road trips. These are people who could afford model S and X vehicles at the old pricing (so 90k+) yet, many of them are eager to make sure they charge their car "for free" at superchargers.
If those people could come home and then power their home on that "free" electricity, they would. If someone is willing to go through the somewhat inconvenience of going to a supercharger to charge their car instead of charging at home, they absolutely are going to go and do that same thing to run their home off of it.
Unless and until this is not possible, we wont see V2H from tesla, in my opinion. This isnt really a "tesla" thing. If there is any free charging in convenient places for people who buy this Ford truck, you can BET business owners WILL charge these vehicles at a free charger, go out and work all day use that free electricity. Why wouldnt they? Businesses try to make money, and if you can eliminate fuel as a cost, thats HUGE.
Of course, whether there is free charging for these ford vehicles anywhere, remains to be seen, but, especially if they have free high speed DC charging, where they only have to sit there an hour to get enough electricity for their daily tasks, they absolutely will do it (and homeowners who buy this vehicle will do it too).
This falls squarely under "this is why we cant have nice things".
