The Rivian R1S is an ambitious electric vehicle that promises thrills and a new feature dubbed Driver to owners. Driver assistance is a must-have feature for vehicles, and EVs are no exception. As EVs proliferate in the automotive market, consumers are more likely to choose an electric vehicle that boasts a reasonable range, excellent handling, quick charging capabilities, and a suite of driver aid functions. With the arrival of the R1S to the electric SUV sector, consumers now have a new alternative to explore in addition to existing models such as the Genesis GV60, Audi e-tron, and Tesla Model Y. Driver assistance systems are automatic aids that survey the road using radar, ultrasonic sensors, and video, depending on the model, may utilize radar, ultrasonic sensors, and video to survey the road and alert the driver when a collision is likely. Examples of such systems include Autopilot technology for Tesla cars, Super Cruise for GM models, and Ford’s Blue Cruise. However, none of these systems are fully autonomous. Hence users must never consider them as substitutes for human effort. Tesla’s Autopilot and GM’s Super Cruise are currently classified as Level 2 of driving autonomy. Usually, these technologies are updated using OTA functionality. EVs are no longer purchased for their environmental benefits. Customers, on the other hand, want greater range, power, and technology, and automakers listen. EVs are undoubtedly ahead of gasoline vehicles in terms of comfort, speed, and handling, owing to major manufacturers’ investments in developing more electric variants. Government policies have also had an impact on the constant influx of EVs into the market. The Driving+ system is Rivian’s proprietary driver assistance technology that improves the user experience while lowering the danger of an accident. While Rivian says that its Driver+ can give clients with real hands-free driving, when activated, it still requires full human attention. Driver+ is currently available for the R1S and R1T production vehicles. Rivian’s Driver+ provides two types of driver assistance: Driving Assist and Active Safety Assist. Highway assist, adaptive cruise control, and lane change assist are all part of the Driver Assist category. The highway assist option allows drivers to enjoy autonomous steering, braking, and acceleration on appropriate roads. Speed can be automatically adjusted with Adaptive Cruise Control, with speed adjustment to keep a safe space between the car and those in front equally available.
