So you're saying that the same subsystem is going to handle my seat
temperature (I prefer not too hot) and the collision avoidance system,
and with the same priority? I don't think tweaking the nice value is
going to help here...  :^)

joke aside, a lot of the default process priorities in Tizen aren't
chosen for IVI priorities. Those will have to be completely
reestablished from scratch to suit the needs of IVI. Most of the
priorities have been chose to favor "user experience" and
"reliability", but it's always a tradeoff. This is why we have
profiles, of course.
