Moto's "polite" cellphone adapts to driving conditions

You may not want your cellphone telling you whether it's safe to take a call, but with evidence mounting about the
dangers of DWT, the phone might just be a better judge of conditions than you are. Motorola is developing a prototype "polite" cellphone designed to determine your circumstances and route calls accordingly. If you're parked, all calls will come through; if you're cruising,
calls on your whitelist will come through, while others are routed to voicemail. If you're in rough conditions —
determined by factors like frequent braking and turning — all calls are sent to voicemail. And if your airbag deploys,
the phone automatically dials 911. Of course, the phone doesn't stop you from making calls, so it doesn't take over completely. But it could help you avoid the temptation to answer every call, regardless of road conditions.
