Smooth Driver helps you to monitor hard braking and acceleration. Why monitor? There are several good reasons to monitor hard braking and acceleration. Minimising these events can improve the following aspects. Fuel economy While aggressive driving wastes fuel, smooth driving can reduce your car's fuel consumption. You can not only save money, but also help the planet by limiting amount of harmful gasses released into the atmosphere. Improve vehicle safety Reduce the risk of nose-to-tail crashes, a common type of accident, by monitoring your braking action. Smooth Driver can help you to see when you brake too hard to stop, so next time you can start braking sooner to avoid serious accidents. Wet and slippery roads require even more sensible braking, so you can adjust warning levels for those weather conditions. Increase level of comfort of your passengers Some people, such as sleeping babies, elderly people and pregnant women, require smoother driving than others. Drive sensibly to make your passengers happy. Smooth Driver helps you to monitor the braking action your passengers experience, which pushes them into their seats when you accelerate, sideways when you turn and forward when you decelerate. Transport goods safely Heavy and fragile goods require extra care when being transported. Smooth Driver helps you to detect safe acceleration/braking level to avoid breakage, and maintain safety under heavy loads.
