I'd be surprised if they ever actually charged anyone with that.
They do in spurts, but not consistently, seeing as how you rarely hear people bitch about it on internet forums
As part of a crackdown on distracted drivers, the California Highway Patrol is not just looking for people illegally talking or texting on their cellphones.
Officials also will be on the lookout for those who are eating while driving. And if you're reading magazines or applying makeup, they'll also be looking for you....
...Although there is no law saying someone can't eat while driving, a distracted driver is in violation of the law.
Under Californias vehicle code, a driver can be ticketed $145 to $1,000 for having wanton disregard for the safety of persons or property. Officers will also be tracking these distractions and the number of distracted drivers, because there are not very good data on just how many distracted drivers there are.
