How can Consumer Reports give a car a 99 out of 100 rating, call it "the most practical electric car we've ever tested" and still not give it a "Recommended" rating? Because of how that rating gets decided. Basically, when CR tests a vehicle, it also needs more reliability data over time to assign that famous "Recommended" rating. That time has now passed, and the Tesla Model S is, indeed, recommended.
