Cars are cars, and static_vector::push_back is, well,
static_vector::push_back. They have nothing in common. You can't
mechanically apply the same rule to both. push_back throwing doesn't imply
operator[] throwing, for example. Their uses are different. A throwing
static_vector::push_back enables existing algorithms that use push_back or
back_inserter to continue to work without their behavior becoming undefined.
A throwing static_vector::operator[]... does not enable anything. :-)
