I would think that road integrity would be on the long list of things covered in any licensing process (you and I can think of it in a few moments, ergo). I would also guess it is important for the system to be able to estimate an appropriate speed even when external data is not available.

For the deer, I would expect the programmed response to be to brake as much as possible given traffic. Hitting a deer is unlikely to result in anything but damage to the vehicle. Swerving is less predictable than that.
