It would be trivially easy to add privacy any number of ways if they didn't insist on tracking the users and logging that info.
They could even track it and just not make it available by web. Or require 2FA. Not exactly a nation-state level attack being described here.
People have just become accustomed to not caring about privacy and so that's what we get.
Yes agree. Drunk driving is bad but bad driving is also bad. Driving in general is also kind of bad. Focusing on the DUI isn't really the solution.
