"Comparable" gas vehicle is doing all the heavy lifting when it comes to tesla's savings.
In my path to reduce my carbon footprint we went from 2 ICE to one and shortly after that one (a Honda Odyssey) became a used Prius. That was too small for us on road trips so after a couple of years we bought a new Prius V. That was absolutely perfect for us. After 8 years, we were ready to trade up for something with better ADAS but effin Toyota had discontinued the V in Canada. Given delivery availability (it was 2020 and 18 months for the PriusV replacement of a Rav4 hybrid, or 9 months for Kona hybrid) we ended up with a MY. Size was important since we park in an underground garage. The My is a bit bigger (but less usable space in the back because of the slope of the backhatch.) Not the crossover station wagon I wanted but OK (height of seats is important to me since I have bad knees/back/hips and getting in and out of the car easily is very important to me.)
When I bought the car and in all other calculations, I'm comparing to my lifetime 5.3L/100km on the PriusV not whatever crap tesla decides I must have been driving and how I was driving it since I bought a tesla. Especially on road trips where the price comparison is to SC, not charging at home.
