It depends on where you live and what kind of unit you’re looking at. Most GPS devices that show traffic get their data from a handful of providers like Clear Channel and Navteq, which collect their information from numerous sources. News of a coming pileup reaches your dashboard as text data over FM airwaves and updates every five to 15 minutes. This system works great for major freeways in big cities, but neither the network nor the data services cover rural areas and side roads, and the FM signal can’t deliver much beyond basic information.
Without any sort of approval from my girlfriend, I bought a 1984 diesel Mercedes-Benz through eBay. Two years later, the vehicle has provided me with nearly 10,000 miles of service on waste vegetable oil (WVO). The fuel may technically be free, but it has not come without a price. Here's how I converted my car, affectionately known as "Chance," to a veggie-oil roadster, and some of the hard-learned lessons I picked up along the way.
