Car Tech forum: Are you for or against GPS and cell phones in cars?

Both vehicles gadgets and mobile hand-held may have good and bad sides as well, when it comes to driver distraction or driving safety issues.
Let alone GPS and cellphones, even instrument panels, radios, CD players,and other conventional gimmicks may pose a serious threat to motorists. Even the specific motorists' peculiar habits may pose threats.
Teenage drivers are causing safety problems due to their one-hand texting knack. Smoking cigarttes may cause some safety issue as well, especially for drivers who ahe less than one year of driving experience.
Legal bans on specific mobile devices are not cure-all. Human enginnering considerations can only optimzie solutions. Some people point to a shift to dashtop mobile equiment in a departure from portable mobile devices.
However, there is a dashtop sprawl of vehicle gimmicks and gadgets. The issues concerning lithium ion battery and mobile hand-held's safety will perhaps drive a herd of technology firms, small or big, to a techno buffalo jump. The question of "Are you for or against GPS and cell phone in cars?" is an awkward question to answer. A better question could be "what could be an optimum solution for mobile devices in cars?"
