A few years ago, I had a protective film put on my model S windshield. you might try that. I do notice some dust scratches on my CT, not sure if I'm going to cover it now.
I was just in Winslow Arizona and got a needed charge at an electrify, 350 charge rate, that they didn't bother to charge me for so yes , a good deal.
I had already bought a special adaptor for the CT as the regular one is too short
standard CC is pretty weak. An auto pilot similar to a Y or 3 would be nice. At least then you could drive on the highway at a set speed instead of wandering up and down. In some ways, my auto pilot in 2019 was a more comfortable ride than FSD is now.
.5.5.2 is a little better, almost good.
but the tendency to cut inside corners, in either direction, is such a pain. and when you take over, you're holding to the offset (and the steering is amplified by the quick ratio), dumping you partway into the adjacent lane.
