You need to compare the SDC to a fully aware human being, not a fully distracted one.
WHAT? What ever happened to "Plan for the worst and hope for the best"? That's how all the engineers around here operate. You said everyone thinks they're above average but are apparently lying to themselves so if the majority is indeed a shitty driver, why would you pretend they're anything else? And also why does someone who is a shitty driver but believes and acts as if he's a F1 driver be a worse problem than a soccer mom absolutely off in lala land? I wouldn't say either one is worse off. They're both equally dangerous and are the number one human factor to attempt to engineer out. A true Mario Andretti isn't the guy you need to worry about, it's the wanna be's and the don't cares that are going to kill you.
any of the banned states could refuse to register one that does not already have an existing registration which makes your end run scenario ineffective.
So, tell me now, why am I still wrong?
