Just did some napkin math and the potential gas savings number seems reasonable. (I expected it to be inflated and still think it's a dark pattern to include it.)

  Model 3:
  (50 kwh battery)
  * (0.166 $/kwh for Los Angeles residential power)
  / (220 mi range)
  = 3.8 $/100 mi of fuel
  
  Average ICE sedan:
  (3.00 $/gal average regular gas in LA)
  /(30 mi/gal)
  = 10 $/100 mi of fuel

If you drive 12000 mi in a year, it comes to about $4.5k in savings over 6 years. That drops a ton if you would have purchased a Prius or other hybrid though, and to zero w/ cheap Texas gas.

So it's a reasonable number if you're a Californian who would have bought a BMW instead of a Model 3. For everyone else, it's likely too high.

That savings also drops to zero if you're coming from another electric vehicle such as a Leaf.

Nicely done math. Based on Toyota etc.’s marketing claims I guess. In which case it might be around $6/100 miles (guesstimate) versus Tesla $3.8/100 miles.
