I totally get that. It’s completely a waist for the M3 SR+ since it only charges as 32amps. My old S was a must as well for the same reasons as you mentioned, plus I was driving it about 2-300 miles a day at times and the reduction in charge time was a must. Another big reasoning for me was redundancy and aesthetics. Obv. I got the signature edition for free so cost wasn’t an issue and install was easy for me. But the convenience of being able to always have my mobile charger in the car 24/7 is a big piece of mind, kinda like always having jumper cables and a hazard kit… a new MCK was the same price as the HPWC if memory serves. With the added bonus of it just looking so clean in the garage. So now that it’s time for number two it just made perfect sense to get the second HPWC so I can run everything off the same breaker and have them load balance automatically. I’d have to install a new panel to do two 14-50 outlets since they can’t load balance and charging two cars exceeds the limits on the 6/2 wires and breaker. Also, I’m out of spots on my sub panel already and it happens to be a 150 panel, meaning I’d have to upgrade the service to it to 200, so new wires from the main and everything. Huge expense and a $hit ton of work. So it’s worth every penny of the 500 for me in this instance LOL
