This charger has been open for a while now... and I've come to the conclusion that it's just too inconveniently placed for many routes. It's "ok" placement for I-85 thru traffic, but that's pretty much it.
4 miles (~5 minutes) out of the way for I-85 thru folks, I-85S to I-77S, I-77N to I-85N.
9 miles (~17 minutes) out of the way for I-77 thru folks.
16 miles (~19 minutes) out of the way for I-85N to I-77N and I-77S to I-85S.
28 miles (~33 minutes) out of the way for I-77N to I-85S and I-85N to I-77S. (Sounds dumb, but it's a common route.)
61 miles (~56 minutes) out of the way for I-85N to Hwy 321N and 321S to I-85S. (Extreme example, but I've needed to do this before the Hickory supercharger was opened.)
Anyway... turns out to be pretty bad placement I think. Doesn't service a good chunk of routes without significant detours and delays. Anything more than 5 minutes off a route is too much, really. The above time estimates are averages... depending on time of day, can be way worse.... but that's not specific to here really.
They should probably open up some more stations in the area at some point to make more sense for other common routes. They could cover I-77 quite well if they open a sensibly placed supercharger is Statesville like I was just noting in that thread.
Anyway, just some thoughts after nearly four years of avoiding this detour stop.
