I'm new Model 3 owner (only have 100 city miles on it) and equally new to participating on a forum. (I hope I don't violate any unwritten forum etiquette rules.) Anyway, here goes. While I know the answer to this is personal, I'm wondering if there's a consensus on about how much remaining range is reasonable to plan for on a long trip. I'm going to drive from CA to Washington, D.C. next Spring and have looked at how the trip might be planned. Some legs between Super Chargers could leave 35-45 miles of range remaining, if all goes as planned. To a novice this seems like cutting it too close, but maybe it's no big deal in a TM3. Love to hear peoples' thoughts on this.
