I'm surprised this option is not offered already. It could be a very high margin profitable option for Tesla. I would pay up if Tesla could utilize some or all of the eight on-board cameras for "dash cam" functionality. What say you?
If the quality and usability was up to par with BlackVue etc., I would pay the same as a good deal for getting a BlackVue installed.
Yes, with 4k camera's at $35 retail, this is a great high margin opportunity for Tesla and a high value option to buyers. With installation costs for two channels running $400 to $800, the installation risks you mentioned plus the cost of the BlackVue, a Tesla option is a no-brainer.
5 Volt power at appropriate locations would also be a nice alternative although not as elegant or as impactful on the corporate profit margins. As far as upgradability, 4k will probably be sufficient for all but the most discriminating videographers.
Ummm. Why do people install dash cams in the first place? I get dropping money on a high end stereo or a radar detector. But what is the appeal of a dash cam?
