???I dunno... Maybe I think common standards are the only way for the whole EV industry to compete with gas infrastructure in the long run.
What if Ford came out with an ICE car model next year that could only be refueled at Ford factory branded gas stations?
Even if they gave the fuel away it wouldn't get very far if most of the gas stations were using the standard that everyone else used.
This is a non arguement. The more apt version of your analogy would be if Ford put out a car that could be fueled for free at their branded gas stations, but could refuel at other stations as well. Given the price of gas, that would be a popular car.
I'm not that worried about different charging standards on EVs at this stage. Technology advances and things will shake out. If there's a need, someone will make an adapter. Since when could you safely put diesel in an unleaded engine just by using the proper adapter nozzle.
