Right now we do not have near the infrastructure needed to support a scenario where a majority of the vehicles on the road are electric(aside from major cities).
you ain’t just whistling dixie. There are several places in the US that host rolling “brown outs” during summer months and peak usage hours. Most major metro areas task their weather personnel with the job of scolding people not to use their electric dryers during the day, keep a/c set at 78F and a host of other admonishments. For most of us, it just rolls off our backs, but, there are several places where this is more than a mere suggestion. Metro-DC; Dominion power has new meters that cycle the power off for you during peak demand and I’m sure other power companies are doing the same.
The additional demand that “plug in” electric vehicles will place on the ‘grid will present a pretty immediate need to upgrade, and there will be power rationing introduced until the upgrades are completed. Even if it’s not a full plug in, if you’re getting any kind of assistive charging from the grid, it will create an impact.
I also don't believe the technology is advanced enough to be practical. The range isn't yet long enough and the charging times aren't short enough to be practical. I'm not saying that we won't eventually get to a place where electric vehicles become viable. But we are a ways out from that place I believe. I think we will see more hybrids and more efficient ICE motors before electric vehicles become the mainstream.
That pretty much nails it. Full electric is an aspirational goal right now, and we’re all kind of collectively sitting around waiting for the big breakthrough, which never really comes. Evolutionary advancements and changes occur over a relatively long period of time to achieve viability. Right now, the cost of a vehicle with “comparable” range and as has been pointed out already, there’s quite a wide variation in range based on external factors, including environmental. I think a stop gap idea may be hot swappable batteries. Michael Czyz was doing this with his 1st gen electric superbike and while it was a bit heavy, in a car this could have some viability. You operate on say 4 out of 6 cells, the 2 standby cells are charging only wheel and/or supplemental generation. as the main cells deplete to a certain level they’re swapped in as active either physically or auto-magically.
In a competition you’d pull the cells and plug in fully charged cells, but we have pit stops for fuel/tires in several racing competitions now so it’s not like this isn’t viable. It’s the day to day usage and time it takes to recharge a street going electric vehicle vs a gas powered one.
