I’m aware of your sarcasm, but it did bother me that my Tesla used a proprietary port that made it more difficult to use other charging locations, such as the charger next to my apartment. Electric vehicle charging ports need standardization as well.
Perhaps having these laws standardizing ports will set the groundwork for a more robust standard in the future. I don’t think there’s ever going to be a perfect solution since there are so many differing opinions, but I do believe this is a good start.
This is happening in europe, tesla is switching to type 2 connectors. I think these laws certainly play a role in motivating the company.
Similarly for cars: as you push for faster charging, you'll need bigger connector pins, though I am sure standard EV ports are sufficiently enough over-powered for the time being.
I love the fact that there is a standardized port, and I can get devices of any type to charge with a single powerful charger. But connector and cables are wonky at best if you want to have a single cable for everything too (look up prices, thickness and lengths of USB-C PD 100W, alt-DP 1.4 capable, USB 3+ speeds cables, and then watch them break in a few months of "regular" use like in a car charger).
But I want a better, more robust standard than USB-C! Can that happen with the law in place? I don't know, but that scares me.
