The batteries need to be cheaper/higher power density though to hit that pricepoint , which is why currently I don't believe it is feasible economicallyOh I definitely think Tesla will build a smaller non-Roadster vehicle than the Model 3 in the next decade.

Not sure about the US but the european crash ratings takes the size of the car into consideration, lots of small cars have 5 star ratings. And the Golf GTI have a overall 5 star rating in the US.
And the crumple zone is the main advantage when for electric cars so i think it would be easy to make a 5 star subcompact electric car.
Golf GTI has a top safety rating, this is true Vehicle details , Official VW Golf 2012 safety rating results
