Hmm, what do we actually do in this case ? Try to filter any gestures
out of the car motion noise ? That sounds painful.
Common wisdom is that you can't use acceleration sensors to measure
large-scale movements (e.g., to enhance GPS performance), because of
their poor low-frequency accuracy. So continuous integration while
driving wouldn't make too much sense.
