Read Whatsapp messages aloud while one is driving!

My car has the option to answer phone calls using bluetooth. Much safer than answer them thru the smartphone. It would be really great if you had an app for smartphones ( in my case Android ) that would inform loudly - "Incoming Message "honey, bring me a bottle of milk on your way back home"" for example, so I don't have to read the message on the phone - VERY dangerous!!
