Off-road vehicle drivetrains. Later, during the 1990s, manufacturers started to add even more luxuries to bring those off-road vehicles on par with regular cars. This eventually evolved into what we call the SUV today. It also evolved into the newer crossover vehicle, where utility and off-road capability was sacrificed for better on-road handling and luxury. To be able to drive off the pavement, off-road vehicles need several characteristics: They need to have a low ground pressure, so as not to sink into soft ground, they need ground clearance to not get hung up on obstacles, and they need to keep their wheels
History of self-driving cars any automated driving systems in use at the time of the crash, which involves a population of an estimated 25,000 Model S cars. In August 2016 Singapore launched the first self-driving taxi service, provided by nuTonomy. Starting October 2016, Tesla says that all of their cars are built with the necessary hardware to allow full self-driving capability at a safety level (SAE Level 5). Due to missing redundancy and sensors that produce reliable data also in snow, fog and rain it is unclear how Tesla will achieve this. The hardware includes eight surround cameras and twelve ultrasonic sensors, in addition
