BMW has a stake in the Ionity charging network, a joint venture of a few companies: https://ionity.eu/en/about.html
BMW also sells home charging units: https://charging.bmwgroup.com/web/360electric-international/...
Your claim is wrong.
I own a Tesla Model 3, my wife drives a BMW i3, my daughter has a leaf.
The ONLY car we can effectively travel outside of the greater Tampa area without major headache is the Tesla.
The ONLY car that I would try to drive to New York from Florida in is the Tesla. (Yes, we've done it.. but would only try it in the Tesla)
One thing I have been waiting to see is a push to have gas stations adopt EV charging on a large scale. Gas stations, particularly ones along interstate routes, often double as rest stops and usually have large parking areas with small marts, and a couple of fast food options. If companies partnered with a major gas pump operator like chevron, shell or mobile to offer even a small number of charging stations with each gas station (even just 2 to 4 at each site in the 50-100kw range.. though the wiring would most likely need to be upgraded to support this) things would shift rapidly I think. I know charge times remain an issue, but if you are taking a rest stop anyway.. the 30-40 minutes of charge is not as big of an issue.
A government subsidy could also be introduced to help offset some of the cost of upgrading these gas stations. An increased tax on Gasoline could go towards paying for such a subsidy. Also I think we need to take another look at nuclear power to help charge those EVs, but that is another conversation.
They're doing that in Europe:

Walmart and Target in the US are partnering with charging networks to put fast chargers in their parking lots:

Teslas come with a J-1772 adapter so you can charge them there as well. Many hotels, airports, malls and parking garages have chargers now as well. I really think we are at a tipping point, one of the annoying things now is when you get to a charger it's busy. Some of the busiest Tesla superchargers you have to wait 15-20 minutes sometimes for a spot to open up.

And in Europe Fastned and Ionity are also installing 350 kW chargers:

The home charging units are nice, but not, I think, what people usually mean when they are discussing charging infrastructure. What people typically mean in that context is "chargers I can use when I am traveling." In that context, GPs "they won't invest a dime" statement is understandable in its sentiment, even if not entirely true. Auto manufacturers do not seem to be taking charging infrastructure needs seriously. Although it is good that this seems to be changing, it's not happening quickly enough.
If anything, the lack of progress on this front is further evidence that the traditional auto companies do not take EVs seriously, and have no intentions of doing so.
