In-car e-mail will soon become a standard feature in most new car models.  As vehicles become more and more convenient, and people are insistent on having all hours access to email, this is only natural.  Drivers will also be able to access traffic updates, parking situations, maps and directions, and weather reports.  You could even use this for purchasing tickets to a show you are on your way to, or scheduling an appointment with your mechanic at the scene of a breakdown.  But some fear this as a serious safety hazard and driver distraction.  While there is already a problem with cell phone conversations and audio system fiddling, why add another one.  So, some manufacturers are programming car PCs to operate only when vehicles are stopped. Others are using voice command systems to read e-mails so drivers can still focus on the road while communicating.  Manufacturers are also still working out reception issues. Right now Internet access is only accessed through cell phone signals. They hope to achieve an upgrade within a few years; with dashboard computers converting to WiMax, (a far-reaching Wi-Fi system)  There are several models that are available now.  The current systems cost between $700 - $3,000 and requires monthly fees.
