So essentially the shock is adding a confounding factor to the focal impairment. The only way the shock can reduce the overall risk is through prevention. You could do that through other less dangerous methods like charging them money instead of supplying a shock.
Great point on the danger of being shocked while driving, though.
Actually, I'm not sure if the overlay is possible, but a phone call would be pretty intrusive and on speaker phone / hands-free would be ok.
It seems that the best course of action would be locking out the user from the ability to text while driving, because whatever signal the user is getting is going to add to the time spent not looking where he should, but when the user can not text while driving, this time will always be zero.
(at least in regards to texting)
I see so many drivers not engaging with what is happening around them, just so they can send some image or read some celebrity gossip or whatever the fuck people are doing on their phones. I think even stabbing them in the arm with a pencil a few times whenever they touch their phone would be less dangerous than letting people continue like this.
I really don’t get it, in the 10+ years I’ve had my driver license I have never texted and driven. Not once. I HAVE had to brake for people on bikes, children, other cars, etc. As everyone has. I have also had drivers who were texting almost hit me while on foot because they weren’t looking up. It is just a matter of time for someone to get killed by you if you use your phone while driving: the street looks empty, you look down to text Bob “lol I know right” and boom, some child just popped out from behind of a moving car and you killed it. Wtf are people doing?
