I have a Toyota Prius & a Nissan Leaf, now Model 3. It's a conscience thing. Plus Tesla is at the cutting edge of autonomous development, so I am looking forward to autopilot. I was surprised by the acceleration & road holding in the Leaf, that now I consider ICE cars to be 'lumbering'. Even the Prius is clunky. The downside to owning a Leaf is I am more sensitive to exhaust fumes & get overly annoyed at diesel vehicles & trucks.
