I have made the trip from Omaha to Kansas City a couple times now. I have made it to the SupC in KC (Independence, MO) with about 10 miles left both times. But I have had problems coming back both times, and both had inclement weather as a part of the problem, as well as me still thinking like an ICE-head and not doing some things correctly. We made it both times, but with problems and L2 stops. The first time we came back into a 50 mph headwind, lost a lot of energy, took a red herring L2 journey (Learned: don't go to a plugshare site without any history to it because it may not be there), got Tesla help and got to an LW, got enough energy and then on to Council Bluffs SupC and home. This last time was worse, traveling in rain with decreasing temps. I stopped in St. Joes for an hour to get power, then I had to stop in Nebraska City to make it. I learned: besides slowing down to make it, turn off the heat (HVAC) as much as you can. Our normal trip of about four hours took nine. But more importantly I was thinking I could make the 200 miles from KC SupC to CB SupC in bad weather. And listen to this: the nav system on the Tesla was telling me to go out of my way, all the way over to Topeka and then north to Omaha. I thought that was stupid. But after taking nine hours to go on 29 as I did, I think I could have gone that way, about 50 miles further, but made it in about five hours. Nav wanted me to go get SupC energy on the way, and though it would have been longer, it would have worked better. I have learned a lot. I, unfortunately, think I taught my son and daughter-in-law to not like EVs.
