use the gps, if the car is going over 20 miles an hour, texting is disabled. the only way to enable it would be to prove you aren't the driver.
this would probably be taking a picture of the driver, or that you are in no way capable of being the driver, it gets sent off to a group of people who just press pass or fail button all day
if you pass, 1 hour unlocked texting, if you fail, 1 hour locked texting, regardless of if you slow down or not.
these 5-10 people who look at the pictures will be payed minimum wage, to 15$ an hour, depending on where you are here may be more or less people.
