Consumer Reports and Tesla really aren't getting along well lately. The what-should-I-buy magazine has lowered the ratings of Tesla's Model S and Model X after noting that a promised automatic emergency braking feature (originally due by the end of 2016) is still missing. The move isn't too damaging for the Model X, since a two-point drop from a modest score of 58 isn't likely to change buyers' minds. For the Model S, however, it's a big blow -- the move from 87 to 85 knocks the electric sedan from the top of the ultraluxury category to third. While few people choose a car simply because it's leading the Consumer Reports charts, it's harder to make your case when you're merely considered better than average.
