Certainly none at Gilroy, which was less than 40 mi. from the factory. But when my co-workers (I brought them as guests on the tour) and I reached Harris Ranch and saw another guy charging at the one supercharger, I have to admit I got a bit anxious. All the more so when we checked at the desk and they didn't leave contact info. After the owner returned and gave me a call about 30 minutes later, I plugged in and filled up while we ate at the restaurant. Getting to Tejon was no problem, and there were plenty of chargers open.
Then, getting over the Grapevine... I was most worried about that when planning the return trip, but it turned out to not really be an issue. It takes more power to get up the hill, and you get some back on the way down, so overall perhaps a 25% boost on power required to traverse the Grapevine.
