I don't want to side track the thread too much, but I feel compelled to reply, since your signature doesn't show that you actually own a Tesla yet. Honestly, I don't really mind. Tesla Service has treated us well, far better than any other car manufacture we've ever dealt with. I gave them a pretty long list of items, they had to order some parts, our service advisor was out sick for a few days, and our local service center is one of the busiest in the country. They simply have more cars then techs. They're working on opening more service centers, but these things take time. I'd rather they keep my car long enough to fix the problems the right way, then rush through everything. Plus they gave me a P85D S to drive in the meantime!
Intersting idea, and one that I've considered myself. I do have a slight astigmatism, but I have lenses that correct for it. I have the ghosting with and without the corrective lenses. My husband does not have an astigmatism and he sees the same effect. Plus, neither one of us sees the same effect to such a degree in any non-Tesla car.
