I am empathetic to but wary of groups who have anti-alcohol agendas. In this recent, NPR piece they discussed various options for curbing drunk driving with automotive technology.
I have spoken about this in the past but considering the refusal by large chunks of the country to wear a simple mask, the chances that drivers will blow into a tube or take an onscreen direction from a car is probably not going to happen.
It is also bad enough that my Prius is probably sending information to Toyota but what if it sends info about where I am and realizes I am near a brewery?
Now, I would not mind if the tech had an opt-in. I would like to know if I am over a limit and need to wait thirty minutes to an hour before driving. Especially if that meant an insurance discount.
This may need to have a stick AND carrot approach.
