Duh. Misread his post, thanks for the correction.

What system is "+8" coming from? In Canada we use dioptres which measures the optical power of a lens, for a near sighted person like yourself it would be a negative number, for far-sighted it would be a positive number. Also there are separate measurements for each eye, and another measurement if you have astigmatism. -8 in dioptres is pretty near sighted but not normally so bad as to require 2 surgeries.

There are challenges faced by those of us living in cold climates. Batteries are less efficient and reliable in the cold, and have the job of heating the interior of the car as well as propelling the vehicle. Did you do any analysis for our situation? Running electric in a climate that routinely hits below -30C is an iffy proposition I feel but I confess to having no hard data.

This article talks about ranges being cut in half in "cold weather", and they define "cold" as 20F. That's a gorgeous warm day in January where I live.

Reminds me of a conversation my friend the Toyota mechanic has had multiple times with Toyota engineers. "X doesn't work/breaks/falls off when driving in -35C." The response: "Why would you be driving in such cold weather?" Because, you know, it's an ordinary January day and we have to get to work.
