         | Teslas has very high, better than almost all other cars, crash
         | test scores for three main reasons:
         | 
         | 1. They have a very low centre of gravity, due to the battery,
         | less likely to roll.
         | 
         | 2. They are heavy (again due to battery), the heavier car in a
         | two car collision always comes off better.
         | 
         | 3. There is no engine in the front, so larger crumple zones and
         | no risk of finding an engine rammed into your legs.
         | 
         | All these properties are the same for all BEVs, Tesla "moat" of
         | higher than standard crash scores is shrinking as other
         | manufacturers launch BEVs.

       | Is there something about a Tesla that could account for this or
       | is it just modern best practices for safety along with a non-
       | trivial amount of good luck?

         | in the same weight class.

       | So...?
