The ARRL seems to be taking a fairly strong position with regards to
amateur mobile operation in the face of a mountain of evidence
suggesting that texting or cell phone use while driving is as
dangerous, or more so, as drinking and driving:

No matter your position on the mobile issue, does it seem to you that
by taking such a stand the ARRL is exposing itself to a boatload of
liability the first time a mobile operating radio amateur plows into
someone on the Interstate and the amateur operation is cited as a
primary cause for the accident?
