Yes, the state of California allows drivers to talk on their cell phones as long as the device is hands free (bluetooth or headphones).  But, as a terrible multi-tasker, I still question the safety of letting us carry on distracting conversations while behind the wheel.  It turns out that I am a potential hazard even behind the wheel of a shopping cart.  
Last week I took a call from Paige while shopping at Costco (hands free).  I was perusing an endcap display with cool power juicers.  So, I chatted with Paige, looked at the appliance, and soon, decided to move along.  
When I reached the next aisle I finished our call and stopped to drop Ziploc bags into my cart.  Sudden confusion...another customer was annoyed with me and claimed I had her shopping cart.  What?  ...But then I glanced down at the cart I was pushing and found it filled with wine, cheese, and products I did not recognize.  
Apparently while focused on my phone call, I wandered away from the juicer display taking another woman's shopping cart with me!  I was embarrassed and profusely apologetic.  The woman softened but still got the heck away from me as fast as she could! 
If I can wheel away someone else's cart filled with alcohol at Costco and carry on with my shopping simply because I'm distracted by a phone call, well, it is a little scary to think what I could do behind the wheel of a car!   
I've also noticed that if I'm talking on my cell when I arrive at Costco I can leave the warehouse and have no idea where I've parked the Volvo!  Costco and phone calls are simply not a good mix for me! Which begs the question: Are phone calls and driving a dangerous combo too?
