An enormous number of people use text messaging while they are driving. In California and a number of other states this is illegal. But that has not stopped the carnage on our freeways. At PFPFP.org we have a proposal that should solve the problem in short order.
A simple change to the law is all that is required. Make it legal to text while driving as long as the driver (also, presumably, the texter) is not wearing a seat belt. Ideally, airbags would be switched off, too, but that presents technical difficulties that us folks at pfpfp are not prepared to take on.
