Found this site with info on a “cell phone taser”...pretty sneaky little thing.
I can’t buy it here in RI
I also saw something called “The Nap Zapper” for drowsy drivers, for a minute I actually thought it was something that “zaps” (like a taser) drowsy drivers.
of course it’s not, it just somehow detects when your head nods forward and then sounds an audible buzzer. (I guess if your head nods sideways you will still wreck?)
