How does the BE 6’s in car camera feature stack up against Tesla’s cabin camera?

The BE 6 Pack Three comes with an in car camera feature, which Mahindra is marketing as a unique selling point. The idea behind this camera is to enable video calls and take selfies, a new dimension to in car experience. But it also brings up privacy concerns, as well as practical utility. For years, Tesla vehicles have had a cabin facing camera on the front dash, and while that's been used for safety and security purposes like monitoring driver alertness and protecting the vehicle when in Tesla's "Sentry Mode", it's never been applied to facial recognition. The discussion of these two approaches to in car cameras also raises questions regarding the trade off between innovative capabilities and privacy issues, and possible future uses of such technology in vehicles.
