It's a dangerous practice that is rampant on area roadways.
No less than 30 seconds after setting up at the corner of N. St. Mary's and Mulberry, KSAT's cameras caught the first motorist texting while driving.
Many driver were so engrossed in their texting activity, they didn't even notice the cameraman -- just feet away -- recording them.
It's a practice that San Antonio police Chief William McManus says is just as dangerous as driving under the influence of alcohol.
On Wednesday, San Antonio Mayor Julian Castro joined with other mayors around Texas to bring awareness to the dangers of texting and driving.
"We are asking every single San Antonio driver to make the commitment, to take the pledge that they will not text while they drive," Castro said.
Drivers are being encouraged to make that pledge as part of AT&T's "It Can Wait" campaign.
The pledge drive lasts through the end of the month. People can text "icwSanAntonio" to 464329 to pledge. They can also visit www.ItCanWait.com.
The pledge to put the phone away and just drive sounds like a great idea, but many driver we spoke with are skeptical the effort will have any effect.
"People who make the pledge are most likely the ones who wouldn't do it in the first place. So everyone's 'preaching to the choir' kind of thing," said one motorist from Cincinnati, Ohio.
"Honestly, I don't think stuff like that really has that much of an effect," another motorist from San Antonio said. "Kids are going to do what they want to do. Just because they say a pledge for it, I don't think that's really going to do anything."
One of the biggest obstacles: the law is difficult to enforce.
"The difficult thing is that the officer has to observe the person texting. Sometimes it really obvious. Other times, it's not at all, " McManus said.
