Yes, using WhatsApp on the road sounds a bit dangerous, but Meta did a good job of adding a version of this app for CarPlay.
Instead of reading your messages, WhatsApp for CarPlay will read them out loud for you. You’ll also be able to get notifications for any upcoming messages and you can dictate a new message whenever you want.
While this app is a great tool for your CarPlay repertoire, please remember to use it responsibly. Even if you’re listening to messages instead of reading them, you should never get distracted while you’re driving.
