The psychology of a reserve is complicated and diverse. I'm a numbers kind of guy so I don't care one way or another, so long as I know how large any reserve is. My wife is most solidly in the NOT-numbers camp and had no idea that the Tesla has a reserve until I told her about it the other week during travel in rural Colorado when a strong headwind looked to thwart our trip planning and leave us short of our destination. As a plan 'D' to get to a charging location she was very appreciative of the reserve since it allayed her anxiety about getting stranded. For those curious, it worked out this way for us:DaveinOlyWA wrote: ↑Wed Apr 07, 2021 8:14 amThe ONLY thing I need is an effective way to monitor ALL my range and lucky me; that is exactly what I have. Not saying it works for everyone since several thousand people a day still run out of gas but...
FYI; I don't live on the edge but I have visited the glass platform that extends beyond the edge several times
Plan 'A' -- drive to destination at usual speeds -- aborted, bailed to plan 'B'
Plan 'B' -- drive to destination at reduced speeds -- aborted, bailed to plan 'C'
Plan 'C' -- Find convenient L2 charging and add a couple more hours of kWh
Plan 'D' -- Stop for the night at the nearest plug
Plan 'C' worked well. This is the second time in 2.5 years of Tesla driving I have invoked a plan 'C' backup. Each time added 1.5 -- 2.0 hours of unplanned for extra charging and travel time. I've yet to experience range anxiety, and I have not dropped below "5% SoC" (not including reserve) to any destination. The experiences are from driving in rural NM/Colorado.
