Market forces may be the impetus for developing this technology...
... but governments will be the biggest exploiters of it.
For example, here in that country West of the Big Pond, there's been talk recently -- at the Federal level -- of introducing mandatory technology that would render most cell phones' functions inoperable when in a moving vehicle:
-- -- United States National Transportation Safety Board
-- -- Gray Summit, Missouri Board Meeting (section "Conclusions," item #6):
-- -- -- -- http://www.ntsb.gov/news/events/2011/gray_summit_mo/index.html
Here's the excerpt:
"#6 Manufacturers and providers of portable electronic devices known to be frequently used while driving should reduce the potential of these devices to distract drivers by developing features that discourage their use or that limit their nondriving- or nonemergency-related functionality while a vehicle is in operation."
The problem with these proposals is that they're (from a technology standpoint) non-discriminatory. For example, how does the vehicle's cell phone inhibition system determine that it's MY phone (since I am the driver) that needs to be deactivated, and not my passenger's phone? What if my passenger wants to borrow my cell phone to make a call while I am driving?
Granted, distracted driving is a major problem, and has killed and injured quite a few people over the years, but no technology can be flexible enough to provide for every eventuality and exception.
