Not quite right
"We'd like to know if it's smart enough to detect you've stopped so you can make a call safely, even if you've left the engine running."
Well technically speaking the law says that to make a call safely you should pull over, and turn the engine off - so if it doesn't work with the engine still running, it's a good feature?
Like the idea in general though, nice idea, even if not entirely enforcable.
