The difference is an adult passenger tend to also be somewhat aware of what's going on on the road and will tend to shut up when things get hairy, even if only through panic. Someone one the other end of a phone won't until they hear the crunch.
Edit: Episode Part 1/3Part 3/3 (I couldn't find 2/3 anywhere annoyingly enough)
TL:DW: They found driving while using a cell phone is potentially as dangerous as driving drunk. They scored lower in their crash course while on the phone
Important to note:
They didn't mention how much alcohol was consumed (or they did in the episode and not in this clip, give me a break I found this in 2 minutes on the shitter)
They show them taking a breathalyzer test. Im going to assume they were testing to be over the limit to get a DUI (.08% in the US), though it's not shown or mentioned A clip of part 3/3 says that they stayed below the legal limit (@ .065%) so they would NOT be legally intoxicated
The sample size is like, 2. Not very statistically accurate, as mythbusters is entertainment and not a real scientific study
Theyre on a closed course. No pedestrians, no stop lights, no other drivers, no "unpredictable" variables in which you would need your reaction time, which would be impaired if you were drunk
Theyre using flip phones held up to their ears, on a phone call. Results probably vary (though are probably worse) texting vs a phone call and on modern devices vs old ones
No real claim either way to one being worse. Moral of the story being get off your fucking phone and don't drive drunk and you dont need to worry. Dreizehn@kbin.social's claims aren't necessary wrong, but they're not necessary right either
