Jammers should be built into every car on the planet. I turn red with rage when I see a woman in her SUV holding up the passing lane while she weaves back and forth chatting away like she's at home. If you have an emergency in a case like this, turn off the car and make your call. Either something like this happens, cops actually enforce the law or I'm going to start running more people off the road. Something has to give.
Another cool scenario would be to buy a beater car, find a woman on her cell phone, get in front of her, block her call and then slam on the brakes. She hits you and it's her fault. Couple that with a picture of her on her cell phone and get her another ticket on top of the accident.
is it really worth all that though? i mean really? being spiteful like this is a waste of time better spent doing positive work.
