Selling dashcams.

What a great business. Dashcams serve to protect you in cases where another party causes damages but denies they were at fault.

The ideal part of selling these is that when one saves somebody money, it’s generally a huge amount relative to the purchase price, and it’s because the camera caught a crazy physical anomaly, or a crazy human situation on camera. Both of which people are happy to share and tell their friends about. Plenty even love to put these crazy events online to share with huge numbers of strangers, and many of them go viral.

This business has a crazy powerful network effect built-in. It’s worth thinking about if you can build one of those into your work.
