I think you slept through an ethics class
There's little evidence that anything Tesla has deployed is an important step towards viable self driving vehicles.
They are apparently mapping the locations of odd situations, but that is pretty meh (and doesn't require the mapping system to be in control of the vehicle).
Ethic issues arise when the expectation is that the occupants will live and then your product falling short on those critical constraint.
Because when you design something for the masses, you are directly responsible for the deaths caused by your product.
This is not a matter of philosophy, from one engineer to another, it's our duty.
