Some developments take place gradually. Such as the development of autonomous and accident-free driving. Partial functions have long since made it to series production. For example, the Active Distance Assist DISTRONIC already provides functionalities of semi-automated driving.
In concert with the Active Steering Assist, it keeps the E-Class in its lane even at speeds of up to 210 km/h. This relieves the driver because he/she no longer has to intervene in standard driving by braking or accelerating and receives significant steering assistance – even in curves.
