Here in wacky California, the law says we MUSt use handsfree cells or get ticketed. Great idea but almost unenforcible. Everywhere I drive I see folks just doing their cell phone thing as usual. Oh yeah, lets not forget those who are "texting" and trying to drive as well!!!!
I love the argument that people can "mult-task". Bull. People can only focus on one conscious task at a time. You're either driving or you aren't.
