That's not the goal. The goal is to turn outdoor billboards into online ad bars. The goal is to micro-target whales, those with lots to spend and who are most susceptible to ads. When such an individual walks down a street they will see billboards targeting them specifically. Everyone will know when the latest tech millionaire steps of the BART. All the billboards will switch from Honda to Bugatii.
Personally, I'm not wealthy. But when I drive down the road I don't want to see the same stupid ads I see online. (At work. At home I use adblockers and never see ads.) None of the ads are relevant to me in any way. I am not looking for a retirement home, nor am I having trouble with my colon. And I definitely do not want to see incontinence products on every billboard.
