You can't use Texas as an example. They have screwed themselves with the power grid and caused the issue there themselves. Poor management in the private power sector that is controlled by a single provider. And nothing has really been done to fix the problems identified two years ago, as evident by the issues they are still having this summer.
Also the "numbers" most deniers are using, to say the power grid can't handle it, are, worste case scenario, max charge rate numbers. Most of the time, you will never be charging your EV from zero, or low battery, at max rate. You will only be doing partial charges at reduced rate. Home chargers are not superchargers. It's a slower charge rate, which is better for the batteries.
