Great Product - Congrats on thinking thru and designing for a "Wire-Free" experience, with Solar batteries and the clever hack of the OBD port connector to offload some functions (wake-up on reversing etc). That said - it seems it is 2-3 years too late to be launching this. 1)By 1 May 2018, all new US Cars will have back-up cameras by law [1] 2) Most Cars sold since 2011/12 seem to have integrated back-up cameras 3)…
And of course there are international markets. China buys more cars than the US, these days.
