you or to your license. Various states have various bits of legislation indicating what is and is not allowed while in motion, but what if you want to have somewhat more specific controls over your kids or workers? That's the idea behind Aegis Mobility's DriveAssist (not to be confused with BMW's Drive Assist), described as a sort of nannified assistant for people on the go. Using GPS it determines the user's "driving context," disabling incoming and outgoing calls and texts and holding messages to deliver later. It's an interesting idea, and given the risks of texting while driving in particular it's a good one, but we wonder what happens if you're on a bus or sitting in the passenger seat.
