we aren't too far away from different battery tech that doesn't require rare earths. Still a few years but certainly getting closer.
As for motor weights, that's already been solved.
Mpg isn't much of an issue with Lecky either.
Range is the biggest hurdle. I've seen the studies suggesting the overwhelming majority don't travel anywhere near enough for range to be an issue, even if they think it is. But I haven't seen these studies break it down by vehicle type. I mean will those with a SUV or 4wd actually travel further than those with a hatchback or sedan, etc. My guess is yes BC apart from the metrosexuals trying to appear manly in their pickups others might actually go on outback adventures with theirs or travel long distances for work and carry/tow good loads.
